how long can you draw a day before you get diminishing returns

If you're worried this much about diminishing your gains, then you are going about your grinds horribly wrong.

In other words; not going to make it.

I can't say for certain but all I know is this, I'll use guitar and lifting as examples.

Sometimes when trying to learn a guitar solo, riff, or song I will play it over and over and just not quite get it. When I try again the next day I've got it down much better than where I left off. Even though I haven't done it in a while, like my brain knows right where to put my fingers without having to really think about it, it's muscle memory.

With lifting, you make most of the gains when you sleep. I am not sure but I have read a few times from a few sources that say your brain absorbs knowledge when you sleep, kind of in the same way you make your gains.

I'd say you're looking at diminishing returns as soon as you start to burn out and don't feel like drawing anymore, when you're too tired, or when you can't really concentrate for whatever reason.

Drawing gains are extremely gradual also so I wouldn't worry too much about it but definitely don't bother if you can't focus and yeah sleep is important.
