I analyzed this a little bit, I think I have a problem when I have to hit notes between the high and low notes of the octave, although fast octaves by themselves aren't so bad. For example, I might be using 1,2,4, and 5 fingers to play a chord. I can maintain the arch on fingers 1 and 5, but then 2 and 4 will have to curl up, which collapses the structure. I was therefore stiffening my 2 and 4 fingers to try to get more strength in them.
I seem to have an easier time maintaining the arch in my fingers if I take high wrist position.
