So, I made a non-optimized Tool-Assisted speedrun/demonstration of posspile the full optimizations of GHZ in this hack. All times are 1-2 seconds faster, but have different techniques (well, 2 and 3 do). Act 1 uses the same technique but does it in a more optimized time, that being 19 seconds, Act 2 and 3 do a very precise trick to make Knuckles glide through the bridge and to wherever you need to get to faster, which is handy. Doing the trick in Act 2 can save up to 2 seconds, tying the TAS time, and in Act 3, you can save up to 1 seconds (maybe 2) either tying the TAS time of 27 seconds or getting a 28. So theoretically, it is humanly possible to get faster times, but its WAY harder to do.
