See my comment on the solution for My Kung Fu Is Stronger.
The section on this final grinding achievement pretty much copies above solution.
I think it could and should address blood spills, because for several characters chances are that you are left with 2000+ pints to spill. That is because those characters spill relatively few blood in their fatalities and x-rays. (Or maybe I picked wrong fatality to do...). Anyway, there are ways to work fast towards finalizing blood.
[edit]
Also, Noob's fatalities are more like sweep than jump distance, I found out (after googling). Please check if you agree and then update solution?
