Taking everything originally said at face value, if you are getting ITM with 15 BB's in 75% of your tourneys, you are gold.
I consider myself to be pretty damn good at tourney play, but 75% seems a major stretch.
In holdem games, without looking at my stats, I might, (on a blusterous day) claim 10% ITM. In non Holdem Tourneys and SnG's I have no problem (this is a blusterous day
) claiming 20%.
The important thing is the money. My BR continues to grow, slowly but surely. Any time I pass the bubble with 15 BB's I figure I got a shot at the top prize. It has happened to me, and I've seen it so many times that as far as ITM goes, the chip leader going in is seldom the winner, and the bottom guy very often can beat that chip leader. Every now and then yeah, you find the freight train that can not be stopped, but more often I find players who have played savvy and now are ready to begin the actual game.
15 BB and ITM, is a fine place to be.
