what's an bad/average/good/excellent winrate in FL ?
Everything between 1 - 2 BB/100 is good, more then 2 BB/100 are exellent. But only with a big enough sample size.
Sorry for my ignorance but what does that mean : 1/2 BB/100
1 to 2 big bets per 100 rounds?
What's a big bet?
BB/100 means how many Big Bets (most of the time with BB/100 you´re referring to the PTBB/100 (Poker Tracker BB = Big Bet) you win in 100 hands.
E.g. You are playing Fixed Limit on the $1/$2 Limit. So the Blinds are SB (Small Blind) = $0.50 and BB (Big Blind) = $1. So 1 PTBB (Big Bet) = $2.
That means if you have 1 BB/100 means that you make $2 on every 100 hands.
I've found measuring your win-rate can become disastrous, especially with the amount of fluctuations in poker.
Making sure you're playing good aggressive poker and looking to see where you lost money, and whether you made the right moves there is more effective. Also look at the hands where you won money and see how many correct decisions you made.
Here's my logic behind why:
Assume you're getting a very good week, and hit the flop hard 80% of the time. Your win-rate is 5 BB/100. The next week, you're unlucky but played better than last week.. your win-rate is now 1 BB/100.
From that you may decide you need to move back to your old strategy, or deduce you're doing something seriously wrong. But you're not.
That said it's much better to go by win-rate than to go by money earned, like you are doing.
altruist is right as evaluating your playing quality AND the playing quality of ur opponents is much better than just look at ur winrate. when u see where the money come from, i.e. the mistakes ur opponents make and adjusting correctly to exploit these mistakes, it is of much more value. there are players with a winrate of 2BB/100 for 100k hands to break even on the next 100k hands!
