Start shallow then work deeper. Remember most buoyancy changes are in the last 10m or so so that's the hardest point to actually control an ascent (and most dangerous).
Start off on dives a LONG way inside the NDL or even at the start if really shallow. Ideally do it next to a line initially because if it goes wrong you can both grab that line to stop the ascent.
The more hesitant someone is to do a skill generally means the less confident they are in doing it meaning all the more reason TO actually do it. And yes AAS should always be with ascents - after all if its needed for real the whole point is to get to the surface. Kneeling down achieves nothing.
