I'm using the effective aperture value = physical aperture value * (1 + magnification) as given in the MP-E65 manual. Seems to work well enough for everything I've thrown at it, although of course I can't say it'll be perfect always.
Liveview doesn't help with the "no light" problem of tiny effective apertures (5x mag and f/2.8 = f/17 effective) and the very short working distance meaning you shadow what little ambient light there is.
