This is something I've found true in my own personal experimentation over the past few years. Any time I've been training something, if I take a break from it, I come back and I have more skill than I had previously.
Recently this occurred with my handstand practice. It's something that I've been working on the past year or two on and off, but more heavily recently. I've made some great strides, but the past week or two I've had a number of things distract me from my normal practice.
Jumping back into it this past week, I've found my balance and strength is or order of magnitude better.
This is only a single anecdote - but I've felt it rings true every time.
