You can check that LRT is correct from the video.

I used the in game timer.

Mod Note: the in-game timer is LRT. The RTA (Real Time Attack/Time with Loads) is usually the video length, and is not necessary to be filled in, unless the run submitted is a full-game (All Heists) run. Since both videos have the IGT of 20 seconds, I am changing the LRT to 0:20.
