The OP is saying it (or something similar), which is why I'm trying to correct his misperception.
The claim that "clipless means less fatigue" is a new one to me, and (again) I haven't seen an iota of evidence to back it up.
Is there a graph showing power output on platforms?
I haven't seen any. I'd also guess that almost everyone who views such tiny amounts as significant will use foot retention regardless.
I find when I am on platforms that I never fully unload the upstroke pedal, and my feet start hurting a lot quicker.
The thing is, I don't think you can make a proper evaluation using subjective methods.
AFAIK the pedal-based power meters will all use clipless. IIRC one power meter (Quarq?) offers left-right, but that's an estimate rather than a direct measurement.
