Improved matching algorithm
When you view a profile we search other trees to find matching profiles. We've enhanced this matching algorithm to greatly increase the accuracy and reduce the number of false positives. Although accuracy will never be 100%, in some cases we've seen the new algorithm cut the number of bad matches by 50% or more.
Note that the new algorithm will only update the match count when someone actually views the list of matches for a profile. This means if you are the first person to view matches after this update you may see fewer matches than were indicated, or no matches. As people view matches and new matches are found the counts will all be updated.
