No surprise that you gentlemen are all over it. This is from my modest little spreadsheet for the Top 4:

VDC - 77%
TT - 73%
HID - 73%

Also, TS+F3 (Supplementary Factor) - 73%
(The header is mislabeled on the spreadsheet as TP+F3.) Given the above percentages, this one is no surprise. It's True Speed or Adjusted Speed Rating plus extra weight for the third fraction. (Page 29 of the Glossary.)

Profit Line and Prime Power are both 73%, too. I added a column for Prime Power and am tracking it independently.
