Mine changes massively if my gf is away or out. If she's away, then I will probably play 400-1000 hands 3 or 4 tabling (incorporating ring, SNGs and the occasional MTT). If she's in, then I tend to play maybe 200-300 in a session.

Importantly, though, I tend to need a good 50 hands plus to get into my groove, so I've gone off sessions where I know I'll only be able to play a short period - I'd rather have 90 mins-3 hours for maximum efficiency (as after 3 hours I get tired or bored more often than not). If I have an hour or so I'm more likely these days to play a couple of SNGs simultaneously, or maybe 5max or 6max IF I think I'll be able to mostly play my A-game (I donk of chips much more rapidly at 6max if I'm not playing well).
