I see that those are the main Block finders :
aHBqmMiMzcHpYd9HSsGWnoLnA5GZ8Rn5KJ(F2Pool)
a69iYfxDwwuCnYdVKqscGSaLS2xfu6hDh5
aGbz8dk7XMs8ViqzTpJivVfZP7t5UmiQPG

What I don't understand is how F2pool finds most of the time 8~10 blocks in a raw!,  there is some serious block distributions problem(lyra2z bug or?).

P.S: I asked before if F2pool pays the Extra luck they get or miners only get what they should based on their hash-rate? there is no stat on F2pool and 4 me as a miner is hard to determine.

Edit: Another "Lucky" day with only 52% of the net hash-See 4 yourself:
