Sure. Not to be a pompous ass but if you don't think so, I think it deters your willingness to learn, adapt and overcome. Though it might not be true, i think it's valuable to think that eventually, one day, you could beat 25/50 NL.

And you second comment was my point. Rule one implies some static state which is just not true. Nothing is static in this game. 2nl 4 years ago would be 8 people going all in. preflop.
