Thanks for the answers, I thought measuring t-stops would've been simpler (although I know that sensors matter and that cameras somewhat compensate for this, you usually perform your tests on the same body for a long time, so I didn't think it'd matter as much, but I trust you that is in fact hard).
By the way, I'm not saying I'd buy an f/1.2 lens for that reason (I don't even own a M43 camera, I shoot on a fuji), what I mean is I think many people (perhaps less experienced photographers) think such a lens would let them use a faster shutter speed or lower ISOs, which is just misleading.
I realize things are complicated enough as is, explaining equivalence (especially aperture equivalence) is problematic enough, I just think consumers in general would benefit from knowing this. For example, say I'm trying to decide between the Fuji 56mm f/1.2 and the APD version, the APD version is T/1.7, so that might lead buyers to believe it loses essentially a full stop, but I'd be absolutely stunned if the non-APD version is actually T/1.2.
Of course, I think manufacturers should report both.
Again, thanks for all your work and explaining why my two suggestion are not actually easy to implement
