worst losing session.. 13 buyins.. or $130.. that was an incredible bad run, but in my record sheet theres a good day of +$146 to account for it.. ie. variance.

I dont use PT because i dont have it, and because the main site i play on doesnt give hand histories but i have created my own tracker than can give me a BB/100 16.5 currently.. but thats only 3K hands so i'm expecting that to change.

in my 48 days of play so far I have had 11 down days, but this isnt a figure of sessions, as there some days where I go down in the morning and up twice my loss in the evening. havent yet made the record sheet advanced enough to look after that much detail.

so the short answer.. yes a losing run once every 5-7 days is normal, i run at about 1/4.. i think it depends on who you play with. If your up against chasers they'll be more often, but your profits on good days will be higher so either way you come out roughly the same i think.
