I wrote a little php script to do the following: Compile a list of the top 10,000 players Request the highscores for each player Calculate the combat level for each player using the best formula As you can imagine, the script ran a while. Personally, I don't believe the combat formula can be wrong by 3 levels. If it is, and this guy really is 85 combat, I'd love to get in touch with him to make sure. That would be a valuable datapoint. I will probably write a script to keep track of these players under 90 combat.
