Also, it seems to me that the size of the AF point box seems to affect it as well - i.e., the smaller the size of the AF box the slower it is and is somewhat less reliable, but it may just be me.

No, not just you: I have had a similar experience, but I must admit that I have not undertaken tests to prove this is true.

I haven't noticed any problems with using the smallest AF box (as I always do on my E-M5). Of course, a very small box can occasionally give rise to problems due to insufficiently strong AF signal (contrast relative to noise) within that box. But that's the same for any lens and has nothing to do specifically with the 20.
