I feel that's a notable performance improvement. Interestingly enough, we had 31 more wins and 31 fewer losses on the way to winning the World Series. The only personnel changes from one season to the next was the acquisition of a new CF (Torii Hunter), a 5th starter (Casey Fossum) and a stable closer (Joe Nathan); so it's not like I bought the championship.
So after all that, my GM rating is a 88/100?!?!? What do I need to do to even hit the 90s, go undefeated?

So what does the GM score mean? Is it just a number only worthwhile for bragging rights? Does it have any significance other than to frustrate you? How is it determined? I'd really like to know how such a performance from a team can be justified with a rating of 88/100...
