This seems to be the key. It's discouraged in the environment I was in most recently because of the resulting upward vector after the bloom potentially jeopardising a non-compromising adherence to sticking below lead at all times at all costs (or at least making it harder to judge potential compromisation), but it seems pragmatic in side-by-side cockpits.

Manage smash ( ie closing speed) with power. At the tip in you want your airspeed to be about 15 % higher airspeed than formation speed ... I want to see the student get on the bearing line early and then ride it in....
Seems to be exactly the same workcycle I use ... HEIGHT - LINE - SPEED, using the same parameters and control techniques.

Absolutely agree. Even after flying stable approach path, risk can be further mitigated by stabilising in a key position before moving UP - FORWARD - IN in clearly defined stages. This also provides an explicit, measurable and teachable/gradable workcycle.
