Histograms of all valid nonces & hashes values

[Geremia]

Could you give us a conclusion to all the graphs apart that :
It makes sense that the nonces found are skewed toward 0 because this is a selection effect: most everyone starts searching for nonces starting at 0, so the lower nonces are found first, even though there may be also higher nonces that could produce a winning  ?

They show nonces are evenly distributed (i.e., equally likely).
