Hey, Faithless1.
The win rate shows how many big blinds you win or lose for every 100 hands played. In your example, where the winrate is 47bb/100, the player wins 4 to 7 big blinds per 100 hands played at his level. For example, the player plays at $1$2 cash game table and with the win rate 7bb/100, the player makes 14 dollars for each set of 100 hands played.
I may be mistaken, but winrate is calculated as follows:
1) Amount of total hands played divided by 100 = hand ratio
2) Convert the amount of won/lost money into the amount in big blinds
2) Amount of big blinds divided by hand ratio
For example, a player made $140 dollars in one session that lasted for 2000 hands. We divide 2000 by 100 to get the hand ratio which is in our case 20. Then we see that $140 dollars is 70 big blinds ($140:$2). Finally, we divide 70 by 20 and we get our 3,5bb/100 win rate.
* P.S. There is also BB/100 or also known as ptbb/100 which are big bets/pokertracker big blinds per 100 hands. This win rate was meant for limit holdem, but basically it equals to twice the amount of usual bb/100. In other words, if you find a graph that says 7BB/100, then it is actually 14bb/100.
* P.S.2 In case you want to use winrate as a reference to your poker "skill", it is recommended to rely on win rate only when you have a large hand sample (like 100.000+ hands played). Otherwise, it may only show some circumstantial values (like you having a bad session/day etc).
* P.S.3 If you ask "what is a good win rate", then my answer is simple: anything that is above 0 which means that you are a winning player. In your example, 47bb/100 is a VERY GOOD win rate and not many players manage to achieve such a nice winrate over a huge hand sample. You can see that even from our small example with 3,5bb that if you play every day a session of 2000 hands and win 140, you are going to do VERY well by the end of the month.
Hope it explained the concept.
