One thing I wondered is whether you could theoretically do a power test in erg mode? For example, could I set my FTP at 350w and try to simply turn the pedals at ~368w for 20 mins?
Failing i.e. grinding to a halt would eliminate the question of whether you’ve squeezed every last drop out.
An FTP test allows some variation in output during the test. Doing it on ERG would be testing whether you can pedal a constant wattage, which is much tougher, so you'd grind to a halt at a lower number.
