Your Kyiv teacher is lucky. Blackouts vary a lot between regions and even within a single town. We have a distributed team and track blackouts in daytime, 8am-8pm. A couple of people had no blackouts so far whatsoever, a few had about 40 hours off out of 60 last workweek. The median is somewhere between 25-30. It is getting worse gradually.
