Depends which way you look at it.
The block at 2014-11-07 06:44am took about 4 1/2 days .. actuallly
Either way, not bad for only 1.2Ph.
Yeah, the time for a single block is from the previous block to the time of the block.
Although you can say we found 7 blocks in a bit over a day, all the statistical calculations including the 1st block of those seven has to include the ~4.42days it took to find it.
I'm still amazed that the 6 blocks averaged less than 10.4% diff for all 6 ...
you are correct that is the right way to do it. but 7 in 27.5 hours sounds better even if it is playing with numbers a bit. LOL
