I don't know that there's any way we could know. I mean if you are mining on your own, maybe we know about it if you are using a solo pool or something, but it's also possible that we never find out about miners working on their own until (and unless) they find a block (and say who they are in the coinbase).

Are the number of solo mined blocks so far higher than they should be statistically or are they in the margin of error ballpark?

Would be interesting if it turns out that for some unknown reason solo miners had a small hidden advantage that caused them to get more blocks than the math led us to believe (/endcope)
