No, based on the analysis below, and within its assumptions and limits.

Each night set against whether you lifted that day, within each epoch.
Within each epoch the two are no more than 6 minutes apart. The bars start above zero so the gap can be seen at all.
For p-values, corrections for testing many questions, effect sizes and the smallest detectable differences, see The statistics behind this below.
How many sets you did that day.
That night's sleep.
Registered on 2026-10-25. Neither measure moved with the day's sets by more than chance would make.
Good and bad nights come in runs, and there are seasons. You asked about both after the result; a second check that keeps runs and seasons intact gives the same answer.
For p-values, corrections for testing many questions, effect sizes and the smallest detectable differences, see The statistics behind this below.
Correlation of the day's sets with that night's sleep, both centred within epoch × weekday; permutation p over 20,000 shuffles within those strata; slope per 10 sets with a bootstrap range; smallest detectable slope; Holm across the six questions tested together on the same history. Added after the result: the same statistic against every whole-week circular shift of the sets series within each run of logging (an exact null), and again after removing a 29-day rolling mean from both series.
| Outcome | Nights | Per 10 sets | Range | Detectable | p | Holm (6) |
|---|---|---|---|---|---|---|
| total sleep | 548 | −1 min | −5 min to +3 min | 4.3 min | 0.64 | 1.00 |
| deep | 548 | 0 min | −2 min to +1 min | 1.3 min | 0.51 | 1.00 |
| Added after the result | Series | Shifts | r | p |
|---|---|---|---|---|
| total sleep | as is | 1320 | -0.020 | 0.67 |
| total sleep | trend removed | 1320 | -0.013 | 0.78 |
| deep | as is | 1320 | -0.029 | 0.54 |
| deep | trend removed | 1320 | -0.024 | 0.60 |
Detectable: A real change this big would just pass the test, about half the time. One about 1.4 times as big would pass it about 4 times in 5. A smaller real change could easily go unseen, so 'no change found' means 'no change this big'.
Each one runs on your own export. What you asked is written down with today's date before anything is computed, so the question stays separate from the answer.
Everything on this page uses history you had already lived. The same test, the same code, on six-week blocks that start after the registration (2026-10-25) is the real check. At a scan every two to six weeks that takes a year or more.
Nothing but to keep scanning and logging as you do.
