I think your calculation is slightly off. hashestowin is the average
number of hashes you need to perform to win the current block. It's
not necessarily the case that a block is calculated each second: in
fact one is found (on average) each 625 seconds[1].

So that gives:

>>> log(171833398380382098659*24*60*7/625)/log(2)
71.23

Cheers,
Joe
