Default How to calculate winrate?

I was reading a thread about a winning player and his winrate is "2bb/100" What does this mean?

this means that on average, after a 100 hands played, he's made 2 big blinds in profit.

for example: you're playing on a 0.25$/0.50$ table with a 50$ buy-in. After a hundred played hands, you expect to have 51$ (your buy-in + 2*BB).

The above is correct for NL/PL. If you play limit, bb=big bets, so for 2/4 limit, 2 bb/100 would mean you average $8 profit for every 100 hands.

Please excuse my newbness but so for example, 2bb/100. That winrate is final? (ie: after downswing? etc)

The best estimate of a players true winrate takes into account all play, heaters and downswings.

Note that most winrates discussed will have little relation to a player's true winrate due to sample size. Unless a winrate is over a sample of 100k+ hands its better to think of it as a description of what happened, than as an estimate of how good the player is.

Correct. Winrate is never final, however, the more hands you play you will statistically gravitate to your actual winrate. aka the law of large numbers.

2bb/100= 2 big blinds/ 100 hands
2BB/100= 2 big bets/ 100 hands
2ptbb/100= 4 big blinds/100 hands, also 2 big bets/100 hands. pt stands for pokertracker.
