Well I omit easy kills such as a player not having items equipped or causing so little damage as to pose no risk. I also have it where if they are already weakened they don't benefit the standings either.

There are cases where you can attack someone who is technically stronger, but if they pose no risk in the fight then they don't count. Their power level must be higher than yours (and of course that is hidden for the time being) and they must actually make a fight interesting to be on the list.
