I bet we've all come across on this type of players. His stats are normal, nothing extraordinary. 19/17 with 5-9% of 3bet and 50-70 Ft3Bet. I usually dont pay much attention to them and I play my usual poker against them. But yesterday I've noticed something shocking. One player with decent reg stats had loss of 39$ on NL5 with 1,5k hand history... On the other table there was another with with similar loss in even less hands, and on the other table I saw a guy with 63$ loss in less then 1k hands... All this players had NORMAL, and by normal I mean reg type stats.
Now my racionalisation of their score was - they are really bad regs that call too often, or bet too often or maybe my hand history was too old? (since I'd stopped playing for couple of months last year).
Do you put any marks / notes on those type of "regs"? Winning / losing reg?
How old database should I use to make sure I got an accurate data since we all, as a players change from time to time. Some players tend to progress, some keep staying on the same level of game and some even get worse o.O
