Why the brutally difficult skip is mandatory for FiNCK 100% WR

There's a very difficult trick in FiNCK that involves (among other things) jumping onto and then off of a bird as if falls past you. This trick allows us to obtain the secret 26th coin in the beginning of the run, which saves a lot of backtracking (both to get the coin, and to get 24 coins to obtain the alternate outfit). The world record for FiNCK 100% is a 24:43, which is not perfect by any standing. However, because the skip saves so much time, it is just good enough to make the skip basically mandatory. On the left of this video is that WR. On the right is a run that represents pretty much the best case scenario without using the skip. See for yourself which one is faster.
The current WR is a 24:43.
