Exactly. Using the multiply-the-listed-duration-by-.85 to calculate the duration at .050 of the big block 676 cam (272 duration, .455 lift), just for one example, you get 231 duration at .050. Actual @.050 duration for that cam is 224.
Exactly, wonder what Mopar Performance was thinking when they devised the ‘multiply by a percentage’ scheme instead of reporting the actual.050 value?
