My wahoo kicker trainer has a very predictable power offset compared to the “true” power that my power meter(s) report. While power-match works well when the bike with the power meter is used, it would be immensely helpful to be able to use this correction when a bike without the power meter is on the trainer.
There are various use case for this, e.g. permanent bike on the trainer, one type of bike with PM and the other without (for those that do road and mountain or TT). In my case it would reduce the vector 2 pedal swaps at least by a third.
How it would work? Just apply a transformation to the power given by the smart trainer. This could be as simple as a fixed offset, better a percentage offset, even better a combination and even better apply different offset at power range.
One way to compensate is by adjusting the FTP % for each workout, but I am afraid that this does not sound very good and definitely will give very erratic TSS.
