If you check out for the previous days, you'd be surprised even more. Somebody's 10 Sat zap is more valuable than a lot of other stackers' so many zaps in hundreds. 
That made me believe one more thing that any game like MM or FFF on SN can be easily manipulated by top ranks. It'd just require someone's 10 sat zap to get the top rank. 

I tried ~music pool with another formula but that went like I won my own pool.

At last, I just wanna say, we can keep speculating for SN algo in the same way as we do for who Satoshi is.

I just checked that out. It is surprising. Maybe my trust score isn't as high as k00b led me to believe.
