I guess a pertinent question is whether those of us using FR630 and FR920XT would still see Avg Stride Length if we didn't use a chest strap (that supports Running Dynamics), foot pod, etc. but relied on the internal accelerometer to determine cadence while running.
While my FR235 does have an internal accelerometer for cadence, I do use a foot pod (and a Tempe). So I'm optimistic that the rev 7.30 update that I "just" did will bring average stride length back.
