Live poker win rate vs online win rate
Live poker is usually measured by money per hour and big blinds per hour. The game moves slowly, so hours are the cleanest unit. If you win €4,500 over 300 hours in a €1/2 game, you made €15 per hour. Divide that by the €2 big blind and you get 7.5 BB/hour.
Online poker is usually measured in BB/100 because hand counts are available and volume is much higher. If you win €1,000 over 50,000 hands with a €1 big blind, you won 1,000 big blinds. That is 2 BB/100.
Why sample size matters
Short-term results can lie in both directions. A winning player can lose for months. A losing player can run hot long enough to believe the game is solved. The smaller your sample, the less confidence you should have in any hourly rate or BB/100 number.
That does not make win-rate tracking useless. It means you should treat the number as a developing measurement. Keep logging the same fields, avoid deleting losing sessions from the record, and review the trend over time.
Formulas used
Live profit per hour equals profit divided by hours. BB/hour equals profit per hour divided by the big blind. Online BB/100 equals total big blinds won divided by hands played, multiplied by 100. Projections multiply the same historical rate over a chosen volume. They are mathematical extrapolations, not predictions.
