Not long ago I was watching I believe Antpool finding 4 blocks in a row and it made me wondering...

Which pool has the highest streak of finding a lot blocks in a row?

maybe asic miner

friedcat

they had a big piece of the network in spring 2013

maybe cex.io they were really big a while back

here is a simple way to figure out odds..

if you have 50% of the network

0.500000 one block in a row

0.250000

0.125000

0.062500

0.031250

0.015625 so about 63 to 1 shot 6 in a row

if you have 40%

0.400000

0.160000

0.064000

0.025600

0.010240

0.004096 so about 244 to 1 shot 6 in a row

if you have 30%

0.300000

0.090000

0.027000

0.008100

0.002430

0.000729 so about 1371 to 1 shot 6 in a row

based on the math above

6 in a row has had to have happened more then once.
