Did you do double blind tests?
No you're right enough, it's impossible to know anything without proper testing. What's the weather like? No point in even asking really without lab testing
Comparisons- replaced my nice ancient shimano with crappy nonseries cranks, all other parts on bike the same. Bit of an extreme example tbh.
Comparisons- SLX vs Middleburn, both on Scandals with fairly similiar kit. Of course other parts are different but I don't see them producing the same effect...
it's not some loss of power or vertical squish I (believe I) can feel, tbh I'd be oblivious to all that even if it was in isolation... it's twist in the arm (and maybe axle?) which equates to the pedal twisting/moving off the horizontal. And the human body is quite good at detecting this sort of thing, it's how we stand up on slopes and shifting surfaces. If you stand on a floating pier you feel even the smallest swell frinstance. (if a pedal axle comes loose I notice it instantly but the play is very small) Probably would also be more pronounced on flats than SPDs for much the same reason?
Now all that said- it's never a problem, not to me anyway. Bikes do lots of things that are interesting but not really important.
