Satoshi Math mistake?
On page 7, where Satoshi shows the Poisson distribution, the probability that the attacker can reach and find a malicious node and reduce the gap by -1.
He has the Poisson formula, multiplied by each attacker's progress, where there is a split function. If k Z in this case.
Shouldn't it be something like, the first case IF K < Z , and the second case be K >= Z ?
