Their voting system is complicated, not everyones votes are counted, and some people's votes are worth more because they are in the top 1000 voters. I'd go as far as to say that that the staff's vote is worth 20-30x as much as a regular voters.
Only advice I can give is that if you give a film a 10 it disappears from your voting history, damnit, vote again.
I personally don't really look at the votes for that reason. I do vote though
