According to what I have learned, what I did actually hurt Lauda's trust rating. Any new unique positive rating will make one '0' (i.e. if you have ? '??). However, if you remove an old rating such as mine.. my rating is 'fresh' now. Aged ratings give more trust points (i.e. that's why total ratings grow over time).
As far as I can see, aged ratings give more trust points,
only if a user has no negative trust ratings.Otherwise, only the number of unique positives and negatives matter. So Vod, your decision to remove your old rating and give fresh rating only helped Lauda move from ? ? ? to 0. It did not (and will not) hurt Lauda's trust rating. However, if Shorena decides to remove his negative rating, then it will have an impact on Lauda's overall trust rating.
