50 Consecutive Votes for Prosser in Verona, which went 75 percent for Kloppenburg?

Not that this would have any impact one way or another, and it is an observation by someone involved in the recount, I still couldn't help finding it interesting if true. From Mark Crispin Miller blog:

Amazing: 50 Consecutive Prosser Base Hits
A recount observer claimed that there were 50 consecutive ballots for Prosser in Verona, a city in which Kloppenburg had 75%.

If true, it is absolute mathematical proof of fraud.

The simple probability calculation:
Prob = 0.25 ^ 50 or 1 in 1,267,650,600,228,230,000,000,000,000,000 !!!

The 50 consecutive Prosser ballots could not have happened by accident.
There you go. So what is the explanation? So how did it happen?
