We have received a number of emails asking why horses do not move up/down when voted on. Without getting too "statistical," here is how the ratings work...
Each horse's HRN Top 250 rating is given a true Bayesian estimate based upon votes from the users. It is a weighting mechanism to adjust a horse's rating score based on the number of votes it has received. The rankings are move than just an average.
This prevents a horse from being ranked #1 in the all time ranking with just a single vote of 10 in the wiki. Thus it is important to vote horses based on ability, not in an attempt to "move them up."
Since these rankings are brand new, it will take time for them to adjust and regulate to the opinions of the community.
