It's usually around 5-12 hrs, as of late. I had to pick up my pace from 3-6 and 6-10 on the weekends. That's online and live combined, tho.
Like today I'm just online so I'll play around 6 hrs or so, depending on tournament variance. For example, the other day I was on ACR and jumped into a micro-trny's 2nd level that started at 6:05am. I went out in 3rd around 3:30 that afternoon. It was a PKO $250 GTD for .55 cents. Yielded around $17 total.
I was under $2 in my acct. All I'd been playing are the smallest trnys they have: $0.11, .25, .55, and a freeroll here and there. I think I made around .45 cents combined in the fr's. It's been as high as $130 micro-grinding. Also, I've yet to make a deposit over there. Everything I've made over there stems from CC freeroll wins/cashes in the trnys we used to play there. Thanx again CC, btw.
Yeah, it all depends on how it's going, too. If I'm running good in sng's then I'll play for something like 5-7 hrs. I can get burnt out easy if I'm not careful. If I find myself thinking about something else, then that's exactly what I'll go do. I'll stop and get off the table or out of the game and do whatever. I've chased losses before, and it never seems to come back when I want. Not the rabbit hole I'm looking for. Happy grinding.
