yes it was a very long round, no more broken than when we found 4 blocks in a row a couple of weeks ago

highest sharecount for a block yes
but with the higher difficulty

if you look at shares/difficulty I don't think its the biggest block yet
BLOCK: 191666 | 16244082 shares | 10h 35m 27s | Amount: 50.06635 | Found by testconpastas | 797.58% of difficulty
pretty sure we had at least  one over 800% before

All I can say is variance happens
