PT calibration question

For the past couple of months, when I calibrate my PT G3 with my Garmin, instead of seeing 506, 507, 504, etc., I now am seeing 564, 567, etc. It still always says calibration successful, but I seem to have lost about 15 watts. The change seems to have correlated with IMTX (post-IMTX to be exact). I don't know if I just lost some power in the build to IMTX? I've been working all summer, so it seems unlikely to have lost that much.

Is it possible that my PT is off (or it was off before and is now accurate?).

Suggestions? I know it sort of doesn't matter (I can still train and race with current numbers), but it is disheartening.

Thanks.

    As i understand it the calibration numbers don't mean much unless that are very different time to time.

    Can you test against something like Computrainer?

    My wife's pro+. Calibration in the thousands.

    My g3 around 100.

    I wear out my PT Hubs every 2 to 3 years of hard use.  When they begin to go, those calibration numbers get more and more wacky.  Call Saris and give them the calibration reading and they will decide if something is wrong.  If you wear it out and it is out of warranty they will replace the insides with all new components at half price.........
