Tyrhold Trial Challenge: Gold seems overtuned

This seems to be the single most tightly tuned dragonrace by a large margin. I have been trying off and on for months and can only get within .2 seconds of completing it, so i figured i must be doing it wrong. But it seems that its just a race that required perfect use of the skyward ascent trick throughout the entire race to even just barely beat the timer.

This seems like an incredibly poorly tuned part of the acheivement and is by far the most difficult part of the Thaldrazus Challenge: Gold achievement.

Am i missing something, or is it just poorly made?
