I've made some rather interesting discoveries recently, regarding the idea of "middling" the action- so it hits the key as full in the face as possible. I've realised that my fourth and fifth fingers were truly pathetic in this respect and that their default movements weren't even close to being directed well. In the past, I think the "keybedding" issue was possibly the problem- as this style of action would be perhaps the riskiest one of all, unless you can keep the arm extremely light and avoid pressing. However, with a light arm, I think it's very healthy- as long as it's paced very carefully and not overdone. When pressing away and keeping the arm light, you can hit the keybed full in the face without strain or impact.
I've found that the simplest way to practise this is to do slow staccato actions, with a desire to knock the knuckle up and away. If you start by missing this deliberately with notably forward actions and notably backwards ones (that both slip across the key), you can start getting an idea where the midpoint is. When doing this staccato, you get a clear feeling of whether you are hitting that mid-point, from how the hand responds to reactions. When it's just right, the finger is still aiming mildly forwards, but there's no slipping and no bracing is needed to prevent any. I've found that standing above the piano or kneeling on the stool is the easiest way to start feeling this direct path, before sitting down again. The closer the finger is to vertical, the easier it is to get a sense of aiming full into the key without slipping.
Anyway, this is making a huge difference to my fourth and fifth fingers in particular. The consistency with which I can play fast runs is being drastically improved. There's also far less time-lag between starting to move and the key sounding. I have a strong feeling that it's getting used to this line of movement that later enables the arm to apply pressure, with the illusion of the fingers not doing anything much. Somehow, they seem to respond much more reflexively, now that I'm getting used to this path of movement.
I tried various exercises based around this with a student who has a very readily collapsing 2nd finger yesterday and I was pleasantly surprised to see a major improvement. There were still a few collapses coming in, but she managed to find a path where the finger naturally stayed rounded. If the finger extends out in just the right path, it doesn't seem to cause the joint to double back- but neither is there a need to feel any sense of inward gripping to resist that. I think the fifth can develop a similar line of movement- where collapse becomes rather unlikely.
