Today was a good day. I spent an hour or so simply playing a five finger scale, with my thumb on Middle C. Backwards and forwards. The fingers are beginning to learn to sit still. And then I did the exercise in PSP on eighth notes, and eventually managed to do it error free. It's C to G and back again, twice, and then C to F and back again twice, all 8ths but the last C a full note as a wee flourish. Then I practised that scale, always in C but up and down the keyboard, and with my left hand, too. The next exercise is the same but in 16ths. I had a go but can't do that yet. However, I couldn't do the 8ths this morning, and now I can.
