I remember when the formula was first posted, I ran it for all of my teams. My overall record was much worse than it should be.
I'm not going to do it now for all my teams, but looking at my 2011 bunch of teams, every single one, but one, has a worse record than it should. Not a coincidence, almost all of them have a losing 1 run game record.
My teams have pretty much always been under what they should (according to that). Pretty much pick a team, and it's doing worse than it should.
So what's my problems? I mean even my winning teams are under where they should be. I don't typically play in bomber parks either, where you can get a ton of runs in blowouts to skew it. Almost all of my teams are in neutral to pitching parks.
I'll give some examples:
This team, albeit winning, is 6 games under where they should be, 18-19 in 1 run games:

This team (5 1/2 teams theme) is 7 games under where they should be, 15-22 in 1 run games:

I can go on and on, but I know at least 80% of ALL my teams have a worse record when using the Pythagorean to estimate it's wins/losses. Am I just that bad?
