I don't want to be that guy
Actually I'd love to be that guy

Did some testing by kicking Uke in the chest and then using the exact same kick on Uke in a replay where I first rubbed his chest (DM is lowered significantly in both replays)

The results are exactly the same in both replays, although the ammount of points received for the hit differs by one unit (40204p for r2 and 40203 for r3)
Interesting

This doesn't mean you're wrong though, it might've always been like this(I doubt the devs change any of the core game code in updates) or my testing may be inconclusive
One flaw source may be how I didn't reach the cap for DMing a new joint in either of the replays, but that seems unlikely to me seeing how I rubbed the pecs of Uke and kicked him right on the spot with a DMT of 15

I just tested it. If you Shift+P through all the bruising to the frame before the impact (accumulating bruises) and hit space you get a lot more dms (5dms) than the ones in the replay. Whereas if you pause at 273 and hit space, you get only the displayed amount (3dms).
Tested in version 4.92.
Pusga did the same in 4.95 and got 5 dms both times. So this is pretty much confirmed.
