You need to look at their individual records. As an example, WrestleStat records a MFF to Starocci as a non-bonus win.
Of the 7 matches he's actually wrestled, he has 4 TFs and 3 Falls. No MDs, no DECs. 100% bonus.
Whereas Hendrickson has two actual DEC wins (Dawson, NDSU and Ghadiali, Campbell), and they record his bonus rate being equal to Starocci's, when it's not.
