I don't agree with the downvotes, and you have a point in that statistics cannot prove fraud. But these numbers do provide strong evidence for irregularities.

Huh? Does that include Moscow with what was it, 47% for UR? Can you name ONE region where concerted (fair) voting by the military can have a significant impact on the outcome?
In any case, your suggestions do not explain the spikes on "nice" numbers, nor the fact that weighting for precinct size does not make UR voting a bell curve, nor the huge differences in the UR vote across precincts sometimes located in the same building.
