Different height and width of the cross-section of the crank arm will change the reading that the meter sees.
There's a calibration you perform with a 10KG weight hung off the pedal. I though the same thing, but it's a self-install PM with no guide to where on the crank you place it or even what type of adhesive you use - other they recommend a two-part epoxy. I thought I'd give it a try, after they said it would work on a Campag crank but I'd need to send it in to be fitted. I can mis-apply epoxy just as easily as they can.
