This isn't useful, to me this only seems useful if the calculations are based on the Raw Points score, then you could see how much is attributed to Match 21, Clean Finish, etc., and include a line "Extra Bonus" that is calculated from the other number you input, or the Total Score. "Extra Bonus" would simply be the difference between the Total Score-(Raw Points+Clean Finish+Stealth+MatchXX+Seeing Red+Butter Ninja). Then you've constructed something useful.
