While doing a 1000 mass run, an advertisement popped up once I pressed play. I reset the time and waited until the advertisement was over, then started back up the timer. I went on to get a 4.18, a new world record by 2.282 seconds. But because I started the timer once I got into the game and not on the menu screen because of the advertisement, is it still a valid run?

Timing starts on selection of Play and ends the Frame that you hit 1000 mass.

I don't have video to see so i can't answer.
