I doubt that many, if any pros, have got stats that good. 40% win rate in SnG's in ridicoulous. How many games have you played. You sure you are not counting only a lucky streak. If you rally have got stats like that give up your day job and play full time.
40% isn't that outstanding actually... not for 9-plyr. SNG's. This is I.T.M. we're referring to ("In The Money")... not R.O.I. ("Return On Investment")
After reading & responding in this thread I decided to pay a bit more attention to some stats. on a handful of SNG's I was playing in (all were 9-plyr. reg. speed). Any player below ITM 37% was actually in the red (not making $$'s, with a negative ROI) although there was the occassional player with an ITM of 35% who actually had a +ROI, must've had a fair amount of 1st place finishes imo.
Just a few more games under my belt since last posting on here and once again checking stats. out of curiousity.... and just on one of the sites I play on for now.... I.T.M. is exactly 40.0%... with ROI +6% and that is 599 games (probably enough for an accurate sample size I'm figuring).

THese aren't 'Big' numbers. They're just a barely winning player actually.
In regards to giving up the dayjob if a player manages an avg. ITM of 40%.... realistically they'd have to be multi-tabling 4 tables at a time for 20hrs. per day to eek out $30K/yr. Not likely in other words.
SNG players who are actually making money (from my experience) are the ones who are doing well in the 45's between $26 & $75 buyin level as there's a bunch of them who seem to manage to keep a 2digit ROI in them. Even on the LowLimit Stars Turbo 45's ($6's) there are a bunch of regs. who do quite well in them... but obviously not well enough to sustain a living from them.
