DAY 27 — The Diastolic at 87, Recovery at 36, and the Gym That Happened Anyway
The data for high blood pressure after a weekend of wine and good food has never been more clearly drawn in this experiment than it is this morning. Three readings between 09:16 and 09:46: 126/87, 119/88, 120/87. Every diastolic reading flagged HIGH. The average sits at 122/87 with a pulse of 74 — the highest sustained diastolic of the past two weeks, directly traceable to Friday evening’s beer and pizza, Saturday evening’s rose wine and camembert, and the accumulated sodium and alcohol that is still clearing from the system two days later.
I went to the gym anyway. Eighteen minutes on the cross trainer and leg press exercises, with a recovery score of 36 — the lowest of the entire experiment — telling me quite clearly that the body would have preferred to stay on the sofa. The body does not always get what it wants.

Blood Pressure: The Weekend’s Full Invoice
Three readings this morning:
09:16 — 126/87, pulse 74. Systolic HIGH, diastolic HIGH. 09:41 — 119/88, pulse 76. Systolic OK, diastolic HIGH. 09:46 — 120/87, pulse 71. Systolic OK, diastolic HIGH.
Average: 122/87, pulse 74. The diastolic at 87–88 is the highest sustained reading since the Day 13 crisis — when the post-social-weekend peak hit 92. It has not dropped below 80 on any of the three readings this morning, and the 88 at 09:41 is just four points below the series’ single highest individual diastolic reading.
The pattern is now documented across enough instances to be predictive. One evening of moderate alcohol: the diastolic climbs 2–5 points above the threshold. Two consecutive evenings of wine and rich food: the diastolic climbs 7–10 points and takes 48 to 72 hours to resolve. The Friday beer-and-pizza evening followed by Saturday’s wine-and-camembert evening has produced exactly the response the data said it would.
The pulse at 74 is elevated relative to the mid-60s that have characterised recent mornings — another marker of the body still processing the weekend. The systolic is less affected, sitting at 120 average with two of three readings in the OK range. The diastolic remains the more sensitive and responsive of the two numbers to lifestyle disruption, as it has been throughout the experiment.
The expectation, based on every previous instance of this pattern, is that the diastolic will begin resolving by tomorrow if the protocol holds tonight: no alcohol, controlled eating, reasonable bedtime. The 48-hour clock started when the last glass of wine was finished on Saturday evening.
Weight: 101.40 kg and the Highest Body Fat Mass of the Series
The Eufy reads 101.40 kg this morning — up from yesterday’s 101.30 kg. The Fitbit syncs the same figure at 101.4 kg. Body fat percentage has climbed to 30.8%, and body fat mass has reached 31.20 kg — the highest reading of the entire experiment. Visceral fat holds at 16 for the second consecutive day, firmly in “Extremely High” territory.
The weight has now climbed from the post-ride low of 99.50 kg on Friday afternoon to 101.40 kg on Monday morning — a gain of 1.9 kg across the weekend. The trajectory from that perspective is alarming. From the perspective of twenty-seven days of data, it is the third iteration of an identical pattern: social eating produces a 1–2 kg spike that resolves within 72 hours. The Day 13 peak of 101.10 kg resolved to 99.35 kg within two days. The Day 20 peak of 100.60 kg resolved to 100.20 kg within one day. This weekend’s peak of 101.40 kg will follow the same path — or it will not, and that will tell a different and more concerning story about whether the underlying trend has shifted.
The body fat mass at 31.20 kg is worth noting separately. This is the first time this figure has breached 31 kg in the experiment. Whether it represents a genuine compositional shift or a hydration-state artefact — the water percentage at 49.3% is the lowest of the past two weeks — will become clearer with tomorrow’s reading after a day of fasting and gym work.
Recovery: 36 — The Lowest of the Experiment
The Hume Band’s recovery score of 36 is the lowest reading in twenty-seven days of tracking. The previous low was 51 — recorded on both Day 25 and Day 26. Today’s figure represents a further drop of 15 points, reflecting the accumulated cost of two days of alcohol, rich food, and late bedtimes layered on top of the 34 km ride on Friday and the 12 km ride on Saturday.
The Strain at 39 — driven by today’s gym session — sits above the Target marker, meaning the body has been pushed beyond what the recovery level supports. The Hume Band’s coaching algorithm would advise against this. The experiment’s discipline says: gym anyway. The metabolic benefit of the cross trainer session does not disappear because the recovery score is low. The recovery score measures readiness. It does not measure necessity.
Metabolic Capacity has climbed to 68, just one point above the Baseline of 67. This means the body is operating at essentially its established capacity despite the low recovery — the systems are available even if the reserves are depleted. The Hume Band is making a distinction between capacity and readiness that is genuinely useful: the engine is running; the fuel tank is low.
The Gym: Cross Trainer and Leg Press
An early morning session at TechnoGym: 18 minutes on the cross trainer followed by leg press exercises. The cross trainer numbers: 231 calories burned, 1.03 km distance, average power 125 watts, average heart rate 142 bpm, maximum heart rate 156 bpm, calorie rate 768 kcal/h. Performance Index 24 and 385 MOVEs. Effort level 4.
The average power of 125 watts is higher than Day 20’s elliptical session at 109 watts, despite the shorter duration. The maximum heart rate of 156 bpm — compared to Day 20’s 171 bpm — suggests a more controlled session at a sustained moderate intensity rather than peaks and valleys. This is the kind of session the recovery score of 36 can tolerate: cardiovascular work that maintains the habit without pushing into territory that would compound the recovery deficit.
The leg press adds to the muscular strain load that has been carrying over from the cycling days. Yesterday’s Resolution data showed 9 points of unrecovered muscular strain from the weekend rides. Today’s leg press will add to that total, and the recovery timeline for muscular adaptation will extend accordingly. The Hume Band’s coaching recommendation from yesterday — keep movement at 40–55% of maximum effort — was approximately what the gym session delivered.
CPAP: 94/100 and the 18-Night Streak
The CPAP scored 94 out of 100 last night with 6 hours 21 minutes of usage and an AHI of 1.4. Mask seal: Good. Two mask-off events. The usage goal counter now reads 18 nights achieved in the current period (9 April – 8 May).
Eighteen consecutive compliant nights. The streak that began on Day 9 has now covered more than two and a half weeks without interruption, encompassing every variety of evening the experiment has produced: conferences, pub rides, late-night YouTube recordings, wine evenings, and early gym mornings. The CPAP has been the single most consistent element of the experiment — more reliable than the fasting, more consistent than the exercise, more predictable than the bedtime. It has become the one thing that does not waver.
The AHI at 1.4 continues the sub-2 pattern that has defined the past two weeks. The therapy quality is unchanging even as the sleep quantity varies. Six hours and 21 minutes is adequate — above the clinical compliance threshold — but below the nine-hour sessions that produced the highest HRV and deepest recovery earlier in the week.
Health Score: 642 — A New Series High
The Hume Pod’s Health Score has climbed to 642, rated “Above Average” — up from 623 last week. A new weekly Health Report has been generated and is waiting to be reviewed.
This is the highest Health Score of the experiment, arriving on a morning when the weight, blood pressure, body fat, and recovery score are all at or near their worst readings of the series. The contradiction is now a defining feature of the Hume ecosystem: the composite score improves while the raw metrics deteriorate. The Health Score presumably weights CPAP compliance, cardiovascular data, and longer-term trends more heavily than single-day weight and blood pressure readings — which would explain why a week of strong sleep therapy and two significant cycling sessions can push the score upward even as the weekend’s dietary impact pushes the body composition downward.
Hume Band Weekly Report: The Cardiovascular Picture
The Hume Band’s weekly cardiovascular report provides the clearest vindication of the CPAP story this experiment has produced.
Optimal autonomic health was achieved on 1 out of 7 days — Thursday, when the resting heart rate hit 57 bpm and the HRV reached 123 ms. The optimal thresholds are defined as RHR below 60 and HRV above 50, so achieving both simultaneously requires genuine cardiovascular fitness.
The weekly HRV range of 63–91 ms is rated “excellent” for nervous system adaptability. The report notes that this range indicates strong parasympathetic function, robust stress resilience, and good recovery capacity. Resting heart rate ranged from 57 to 75 bpm across the week. Baseline SpO₂ held at 97–98%. SpO₂ consistency at 97–98%. And zero low SpO₂ warning events across the entire week — the same finding as Week 1’s report, now sustained across the full experiment.
The optimal HRV range is listed as 109–125 ms — which is considerably higher than the daily HRV figures reported by the Hume Band. The daily figure and the optimal range appear to use different measurement windows or methodologies, creating yet another layer of interpretation for anyone trying to understand what these devices actually mean by the numbers they produce.
Where Day 27 Sits
Three days remain. The body is carrying the full cost of a weekend that prioritised pleasure over protocol, and the data records it without sentiment: weight at its highest since Day 1, body fat mass at its highest ever, diastolic blood pressure at its second-highest sustained reading, recovery at its absolute lowest, and visceral fat back to 16. Against that: the Health Score at its highest, the CPAP streak at eighteen nights, the gym session completed despite the recovery deficit, and a cardiovascular report that describes the autonomic nervous system as excellent.
This experiment has always been about the tension between these two pictures — the flattering composites and the blunt daily measurements, the devices that disagree, the body that responds to wine and camembert with the same honesty it brings to cycling and fasting. Three more days of data will not resolve that tension. A Phase 2 in May, with the CPAP locked in and the device framework established, might begin to.
