Just a thought. Ignore the middle of the video where the thing gets caught in the field. Since exfu flying is the fastest way across, coming out going up slightly should be the fastest route there is. The only possible improvement that I can think of would be to have enough height when you first cross over the portalable surface and then dropping down and popping back up. Although that might not even save time but I don’t know.
Also I suggest the crouched version of this glitch because I feel it’s easier to get and you can drop easier once you reach the other side.
