If you've pushing things, not used your fingers, or used your hands and fingers (pushing them) doing other things, then when you come back to the piano, things would be different. That's happened to me many times. I think it's just part of how things are, regardless of what level you're at. If you have pushed thing, it's not necessarily bad because good results are on the way -- The hands are just recovering.
jgallag: There are times that stress, tiredness,feeling overwhelmed and make the fingers not do that *fingerpower* as you indicated in your post.
Practise earlier in the day then.You ladies tend to wear your hands out during the day doing washing, ironing and other menial tasks. Thal
