I notice that many of the x50 and x100 blocks are mined to addresses that have only recieved 1-2 block ever in their respective transaction history.

4 out of the last 6 x50 or x100 blocks have been mined by lucky solo miners?
Do many miners switch to solo mining just before the x50 or x100?
Thoughts? Am I missing something?
On steadyminers we got 2 consecutive *100 6-7 hours ago. I don't know now
