Just to shed some insight, Full Thrust and Chaos Thrust are the two 'fastest' executing abilities through which you can chain a jump and both have interesting sound cues to help you time.
Full Thrust has you lowering your polearm and then jumping upwards, there is a 'charge up' sound and then a 'release' sound that happens when you're halfway through the jump and didn't reach apex yet. The point in which the animation can be cancelled into a Jump is roughly when the jump is at it's apex and if you press the jump button at about the time the 'release' noise has went off the jump will actually go off in a smooth motion, having spent about only half a second of hte GCD (it also looks cool as hell).
Chaos Thrust has three distinct slashing noises and a fourth 'finisher' noise. I can't help out much with the timing on that, i'm WAY too used to the noise from 1.0 which was a good 3 seconds long, but I did realize that you can cancel into a jump before the 'finisher' noise, however.
