When sliding this performance marker,OT2 says that the 5575 is too weak as well if you match speed to what AA says.So it can be calibrated,just need to know how to do it.Wonder why they couldn't tell me this when I talked to them.
Even in the helpfile they tell you to just change the IBO speed. Perhaps that was before they changed it to cams instead of speed.
But yeah, changing the performance slide does work for adjusting for spine. Great catch!
