i'm 100% sure
and in a slotmachine, the kite will flare out

Argh... I hate to admit it
but you are right once again...
Yes, after seeing your videos and the original I do see it is a 540 chained to a slot.
Now, that doesn't block me from trying to get what I thought I had seen!
In other words, a fractured 540 when having done 360, then pulling it down a little, starting a new 540 which must be fractured again, etc., as many times as possible.
One new trick...? Perhaps not but I want to try it.
