If anybody else is lurking here or stumbles across this addon...
There's a slight adjustment you can make if you are a human.
If you open up the BloodReputation.lua file in Notepad or some text editor, you can change the reputation value per bruiser kill. This is very useful for humans w/ the reputation racial.
At around the 30th line of text, there is the following string...
"local POINTS_PER_KILL = 25"
if you're a human, simply change the 25 to 27.5.
This should decrease the kill count needed by about 10% (obviously) on the tracker in-game.
