All the above is about me, but my reason for sharing is that it is interesting that the exif data contains enough information to answer questions about AF speed at light levels, AF speed for a lens at light levels, ... The idea is if you are interested, there is a way to actually quantify a lot of the general arguments about AF speed posted here.

Ah, that explains it. I misunderstood your reason for posting the graphs. You were just pointing out that EXIF contains enough parametric data for us to do our own data gathering. Thanks!
