I guess it depends on the performance. If you can fit 5 Duolingo lessons in 10 minutes a day. That is enough to be able to speak somewhat, it will just take longer than otherwise often, because I guess the more you do in one session, the deeper you go, sort of in an exponential manner. Although I'm not completely sure about where the top and bottom limits where the curve starts and stops being exponential... Let me know if that makes sense.
I guess after listening to "The Sleep Revolution" by Ariana Huffington about 6 years ago I started believing 8 hours were the needed amount. Nevertheless I discount 15 minutes from the time I close my eyes supposing it is the time it takes to fall asleep and usually at least 2 pauses of 10 minutes at night for peeing and water drinking, sometimes 3.
So even If there were 8 hours from the moment I closed my eyes and until the moment I woke up, it could easily end up in 7h 25m or 7h 15m, or more if I drink water aswell and move slowly.
In any case I do not feel sleep deprived, as far as I'm aware, mostly. If I do sleep 4 hours or have a day where I plan to not sleep for some 20 hours straight, I try to plan in a nap, or compensate the next day. But one such day really doesn't have such consequences on the feeling throughout the day as far as I noticed. The problem is when it repeats itself.
Having 6.5 + hrs a few days in a row also doesn't cause me much drowsiness...
