After watching your videos sliq, I noticed you used a technique similar to the Murder Kick Cancel, but involving the Murder Choke. However, you have no section labeled Murder Choke Cancel, so I went to go check it myself. I'm hoping you'll add a section, because I find this significantly easier than MKCing, albeit more dangerous.
To start, you must be a distance away from the edge that will allow you to go over it with the Flame Choke, normally causing a freefall. The exact distance is pretty lenient, though if you're far enough back, you'll stop yourself at the ledge. After initiating the Choke, just hold back on the joystick. Ganon will go over the edge and immediately sweetspot it.
The reason I say this is easier is because it doesn't require a knowledge of distances, like the Murder Kick does. But it's more difficult because you enter "helpless frames" from the Murder Choke, so if someone grabs the ledge before you, you'll die.
Hope this helps in some way.
