It's a little complex. I hope it helps.
The removal of 440 from the total is to make Tracy and HM comparable. Then, since Tracy is the same, I make both the same. But to do that I have to remove 360 (Tracy) and 240 (HM, calculated based on Tracy) before I can compare all three of them in units only. It's quite complicated. Hopefully you understand or someone may give you an easier answer.
