How would I go about converting the time shown at the end into mm:ss:lll?

(L stands for milliseconds)

The time at the end is "seconds.milliseconds". So you can convert it in minute and second with the milliseconds at the end. If i have at the screen "260.4" that means i have 260 seconds and 400 milliseconds. And 260 it's 4x60+20. So i have 4min.20sec.400millisec.

Now I’m just waiting for the mod to verify my runs. :)

Your good
