Helping Average Out Values

I need help. You can see what I've done @ http://egsl.enguards.net/lolurdumb/singles.php?mode=matches or ?mode=scores
Anyway, this takes fights from an online game and records them to this site, which then displays a top points/scores list using the formula (avg. hearts left)*((win%(10000))
The thing is, I'm noticing the averaging of the hearts takes the players CURRENT average hearts, adds it to the # of hearts they are left with the next match, and divides that by 2, rather than dividing it by "match_all"
For example, if a player has played 4 matches and his current HP is 4. The next match, he wins with 2 HP left. His average hearts now displays as 3, rather than some decimal below 1.
Can anyone please fix this for me?<?php

Anyone?

I usually dig these kinds of issues out by adding echo statements of variables before and after the relevant calculations. That gives you helpful info as to how the calculation is going astray. I obviously can't do that with your script.
