I went bacj and checked the numbers, and based on your current system, V2 fire rush beat shrieker rush in game 3 by a nose.
Ahem... I went back and checked 
13.8273 for shrieker rush
14.1676 for lava rush.
I DECLARE THE WINNER TO BE FIRE!
A matchup between v2 and vNG is needed

actually i'm not sure that V2 would have won against shrieker.... since i would still have to do the adjustment for long games. (by turning some wins into losses)
but for some reason i can't find that one spreadsheet so i can't give the adjusted numbers.
therefore... who knows who would have won ???
*edit*
but jmdt's speedbow would have won, even after "Long Game Adjustments". with a score of 12.66 to 12.78
