Second Ukrainian legend of Polyphasic community, moderator of russian telegram chat, master of zero-REM naps and just a good guy. Slept on some version of E1 in school, but seriously started poly in august 2020. Holder of the biggest adapted nap gap on E2. B-)
E2
Adapted without big problems (overslept once on ~day 18) in about 30 days (steadily started to wake up before the alarm on the core). Stayed on it totally for 80 day, then tried E2-shortened.
On about day 40 I got my zeo sleep tracker and observered very strange and low numbers of REM. This explains why I remembered so few dreams on mono. And almost never on E2. Numbers were very random (the biggest was 60 mins on core and the least was 10 mins). On naps I got almost zero REM.
E2-shortened
The main reason of changing schedule was my compressed SWS sleep. I got all of needs in first 2 cycles.
