I have observed similar things and so far the relationship continues to bewilder me. At times I return with a better ability for something I haven't touched in years, while when I was actively training it, improvement was slow. Perhaps some cross-pollination from another source, but still strange. It's... not always encouraging, as at times it's very hard to say what has improved it and whether practice is all that useful.
