Has anyone else noticed this?

For the first couple of weeks I thought it was my imagination but hundreds of games later in conquest and vs. cpu I am convinced that on pitches that split the strike zone lines 50/50 anywhere (or even a little less) are strikes for the cpu pitcher 95% of the time and less then 40% of the time for me. It seems like less then 20% of the time!
I play on all-star, sometimes HOF.
I know umpires supposedly have a little different strike zones from one ump to another (or so the announcers sometimes mention) but I am sure all these umpires are "homers" lol.

Yeah it's probably my imagination LOL.
