I ended up using something like ... 1/2500 @ F2.8 1/5000 @ F2.0 1/8000 @ F1.4 The shutter speed max out at 1/8000. So in theory, the F1.4 is overexposure by 25%? Eyeballing the resulting RAW ORF files, the 1.4 is actually darker, so it may support your theory that the difference is less than the one stop. All the other files look similar, except that *may be* at F11, it is brighter by a tad, but may be it's the cloud moving away :-) Not very dramatic though. F16 is fine again. So not very scientific, but may support your thesis... Oh, I do have both the 50/2 macro and the 90/2 macro, and they do look wonderful with the E-3.
