Hi arriusdaze,
The scoring algorithm on the Official GMAT is far more complicated than most people realize. It takes into account a number of different factors, not just the number of correct and incorrect answers. As such, you shouldn't be spending time trying to figure it all out. You'd be better served working on building up your skills.
Since that algorithm is proprietary, no GMAT company has an exact match for it, thus CAT scores can vary a bit based on the 'biases' involved in their respective designs.
Since your goal is ultimately to improve your scores, a far more useful gauge would be to review each CAT and determine how many questions you SHOULD have gotten correct, but didn't (due to a silly/little mistake). Those mistakes are the things that you have to fix to score at a higher level.
1) How long have you been studying?
2) What resources have you been using?
3) What is your score goal?
4) When are you planning to take the GMAT?
GMAT assassins aren't born, they're made,
