Hourly income per level for best players in the world here:
http://www.blackrain79.com/2014/10/how-much-do-poker-players-make.html
imo: For good player (per level) half the income, for reasonable player the income is about 1/3rd of calculated.
So if one day I’m good at NL10 I should be making about 5 dollars per hour, if at NL25 10 dollars per hour. After that I think it gets quite hard to get to good category and reasonable category is what is most likely if ever, making income at NL100 for most around 13 dollars.
If we assume live NL200 is similar to NL5 online we are expecting 17bb winrate, 20 hands per hour (breaks and all), 6.8 dollars per hour if you are very good. If we assume live is more like 2NL double that hourly.
EDIT: I just notised a flaw in my thinking that alters results somewhat. These win rates by blackrain are calculated while multi tabling, in live you are single tabling and have time and data to really know your enemy.
