don't worry about the numbers too much, if you're a winning player consistently and your performance is being affected by trying to get your stt's in, then it surely isn't in badbeats best interest to make you play so much.
the plan has to be to make money with minimum risk to badbeat and yourself so reduce the risks and play your A game
i'm in exactly the same situation, kids, job, mortgage etc and i've given up trying to get my hours in. if i do, then i so but if i'm knackered or in a bad mood, i just don't bother as i know i'm going to spend the rest of the week clawing back the mess i make when i'm playing tired just to get my number of hands in.
occasionally still,i do play tired if feel a bit guilty that i haven't played for a couple of days and 9 out of 10 times, i play poorly or lose concentration quickly. so in the long run, i am actually wasting the time when i feel like playing clawing back losses first.
only my opinion and i'm not saying that you should hardly play but if it's affecting your game then it doesn't make any sense to play so much and a good roi over fewer games reads better than a mediocre roi over loads and has to be more enjoyable
good luck
