You can see it employed in my Hoth record run:

No problem! Good luck, as far as I know, I'm the only one to successfully incorporate it into any runs so far. And I didn't even do it on the third because I was taking out the AT-ST simultaneously.

As a follow-up, I think one needs to hit checkpoint zones around each of the four legs. I made a diagram for reference. You would latch onto leg 4 in this example.

You need to circle close enough to the inside of the rear legs (3 and 4). Circle too far forward and it's no good. Cut diagonally (and don't get close enough to 3) and it's no good. If leg number 3 is lifting toward you though, then you can cut diagonally a bit because it's zone is closer to you. If leg number 4 is lifting, it usually means leg 3 is farther back and it's harder to hit zone 3 and swing around to squeeze between leg 4 and the body and not explode.

At least this seems to fit my experience. Hope it's helpful.

It's up to MDK, but I've been calling this the "trip-skip".

MDK discovered this one. For example, if you are in cockpit view and just before you reach the "cable out", you switch views, the cable will release but you will be free to fly around during what would have been the cutscene. I think you have to be still in the transition animation between views when the cutscene triggers (skipping it). After the cutscene time-period ends, you will warp to a spawn point. There isn't much time to do anything before that spawn, but you can set yourself up for a spawn in a better location. One example is after the second AT-AT is the following video (about the two minute mark), where I skip the cutscene and fly to the ridge so I spawn next to the last AT-AT rather than by the previous two.

I think many of us have wanted to wrap an AT-AT by going through its legs without going all the way around, but the cable always releases when you try. I finally managed to pull it off:

My initial guess as to why I got it to work (attach point being in the middle) was incorrect. Basically, if you attach it to a rear leg, you have to go around and through the middle and pass close enough to that initial leg to make the game think you've gone all the way around. If you don't, the cable will release. I think this can save between 3 and 5 seconds per AT-AT.
