Vod's previous ranking was based on trust score, which as you know became stronger over time. Given that that score no longer exists, I assume the new ranking will simply be based on number of unique positives minus number of unique negatives, unless Vod wishes to implement a new formula. This would likely mean many people sharing the same rank, as positive scores are now in the range of 0 to 66 instead of 0 to 660.
I don't know if this will make a big difference for users like yourself who have lots of unique positive ratings and won't share that exact number with many other users.
After further examination this is also my conclusion.
