I think 1 SnG is equal to about 1/2 hour of limit play, figure about 60 hands per hour, so 100 SnG's would be about 50 hours, or 3000 hands. All very ball park.

True win rate is very elusive, and can take literally thousands of hours. It's possible for a good player to have 500-1000 hours playing behind, so that would translate to many, many SnG's. I think under normal circumstances, a decent win rate after 500 hours coupled with a solid understanding of poker theory, would indicate someone is at least a decent winner at a given limit.

One problem with all of this is, by the time you've played enough to get a fix on win rate, the games will have changed and the player will also have changed, usually for the better, but not necessarily. One of the things that keeps poker alive.
