I did sprints today. Garmin Vector 2s had no issue measuring high power output, or cadence during high powers, as pictured below.
Then I did cadence work, in my smallest gear (39-32).
Cadence seemingly capped near 140 and plummeted to 40-60rpm reported once my power output decreased (while my ACTUAL cadence continued to increase, of this I am certain). I'm quite certain I was over 180rpm for 3 or more seconds, and if I had to guess I was probably in the range of 220-250rpm momentarily, but I've never really tested before. (I'm a former bobsledder with the power profile you'd find in someone like a linebacker on a bike).
Given my speed, gear ratio, and wheel and tire size, I suspect I may have momentarily surpassed 250rpm.
Is it possible that Garmin records cadences over 200rpm as those same cadences but subtracts 200rpm from them? That's what the data looks like if my math is right. See below. The red zone indicated below is a period where I am absolutely certain my cadence was increasing.
I would love to know if I can rely on Garmin Vector 2s to do this 200rpm subtraction reliably or if this was a fluke. Can anyone chime in?
