Well, I retimed both runs to the frame and it seems: Your run is 6:38.533 My run is 6:38.467, or .500 depending on when time actually ends. I personally don't mind if you want to add milliseconds or not. It doesn't bother me to share the WR.

Oh and btw the splits are the same ones I used for Tails attempts, so that's why the Sum of Best is so low.
