Average FTP depreciation rate per day known?

[Shrike]

I know on Xert it runs a -1watt loss per day if you’ve not been on the bike, but no clue if that’s worth anything.

Say you do nothing, is there a linear or non-linear depreciation. What if you do endurance only, does that mitigate the depreciation over no riding.

Is this stuff known/studied or is it too wildly different between people?

Maybe not the hard numbers you want, but this is a good reference:

How much training volume does it take to maintain ~3w/kg?

Here is some info that may be helpful: Training Residuals: Aerobic Endurance – Establishment: 25-35 days; Residuals: 25-35 days Anaerobic Power – Establishment: 14-22 days; Residuals 14-22 days Muscle Endurance/Threshold – Establishment: 10-20 days; Residuals: 10-20 days Sprint Power – Establishment: 2-8 days; Residuals: 2-8 days Declines in Aerobic Capacity: 1-7 days: negligible decrease 10-14 days: 6% decrease 14-30 days: 12% decrease 30-63 days: 19% decrease >63 days: 26% decrea…

Wasn’t expecting the residuals from threshold work to be so long. Up to 20 days! Very interesting…
