I've been tracking for a period my hour rate and I want to know how much data I've to collect in order to establish my winnings per hour. I've been searching online and when it comes to getting a handle on real-WR potential 50k hands (1600 hours) is a starting point, 100k (3200 hours) is pretty good, and 500k+ (16200 hours+) is solid. But I'm not sure about this and I would like to calculate it myself. Any help?
The problem I see here is that if you are starting to become a professional player, your skills should be improving, thus I think you should track your performance based on shorter period of time, say per month or per three month. You can then test if the increase of your hourly rate in each period is statistically significant (assuming the increase is a constant).
