Hey Juan,
50 votes for one submission is extremely rare.
I would be shocked if any submission has EVER received more than 100 votes.
Since I began tracking this stuff, the largest voter turnout I have seen was for Duc's Centipede submission:

I can't provide the exact voting result, because it completed at the same time as another submission. However, I have estimated the final vote tally to be somewhere between 78-0 and 82-0 (based on various parameters).
I don't know what the minimum requirement is, but one submission was pushed through by only a 6-0 vote (the fewest number of votes I have encountered for an accepted score).
I suspect the precise adjudication algorithm shall remain a mystery.
