Ah, good point.
I'm pretty sure I saw the ability to turn off the auto-zero when I looked at the settings on my Quarq the other day.

Quite possibly, it's a while since I last had to play with Qalvin. I've never really understood why it isn't offered as an option universally. The extra code would be minimal, I would've thought.

The USE chainring means you can use road cranks on a track bike, but it doesn't solve the problem of the auto-zeroing giving bad calibration results on a fixed gear bike. You need some way to turn off the auto-zeroing, which AFAIK was the only difference between the normal P2M spider and the track one - the track one had auto-zeroing disabled, which you can't do with the normal one.
These days I believe it's SRM or nothing for track crank-based PMs.
