After a fairly steady ride on Monday my garmin notified me of a new FTP to save or skip during ride summary - 23w/kg, 1658w. Which is perhaps a tad optimistic. I'm running a stages single crank arm power meter and checking the figures my peak power was miles below that.
Then today I got similar but bumped FTP up even higher, didn't get a photo this time but think it was in the region of 2300w. Average power for the ride was nowhere near this obviously nor was the peak power.
Only seems to be happening since the last update though it seems other garmins have had the same issue in the past.
