When I first started riding my cadences was low but I didn't know it.
After some knee issues, started reading on how to fit the bike & importance of cadence.

Worked at getting 80 cadence, watched the clock on Cateye padrone, counted
cadence for 15 sec , then x 4.

Now, into 4th year , G-520 for 1.25 years, my comfort cadence is ≈85 - 95.

The 520 gives me a cadence ride average, but I think the average is wrong.
Sometimes it's in the high 70s.

How does it calculate the average ?
I think it's , pedal strokes/ride time minutes ? )

I don't need or want the average to include the times I'm not pedaling, coasting (cadence 0).
I want the average cadence to average it only when it matters, when I'm pedaling.

Any one know how it's calculated.? or
can I choose how it's calculated ?
