i've recently been wondering if it would be possible to do a clip in the above ground section of 4-2 on the stairs(sort of like the pipe clip in 2-1) in alternative to running over the stairs and going backwards into the warp zone to save some time. Any input on this idea would be appreciated.

What if we make a catergory called portal minimum jumps? I can do about 5 minutes with 2 jumps first try.
