What are typical numbers for chakra reserves and regeneration times in Naruto?
It really depends on the Shinobi, I mean if they strain their chakra reserves by doing a bunch of exercises, in theory their reserves will grow. Regeneration time depends on the time you rest. If you're asleep you have a faster revival rate, but if you just sit still you'll have a slower revival rate, and if you're active (even if you are not using chakra) you'll have an even slower revival rate.
