What the speedrunner does, is just use their irl stopwatch and count it to 10 seconds:

Meaning the timer there is moving to 10 seconds in real time. Now the bunny hood can fully count the 10 seconds:

The Post-Man then acknowledges you doing perfectly 10 seconds saying you have good reflexes.
So DMC's would need.
A. To fall under objective real time.
B. Have the characters in-universe acknowledge it.
C. Specifically require the speed amp for him to do it.
D. It be canon.
