Yes. This doesn't feel new to me. I was just researching last year on "muscle memory" trying to understand what I could expect by getting back to lifting myself from an actual science and study point of view. This versus the bro-science-cum-common-wisdom of muscle memory. What I was turning up didn't seem particularly new, but the consensus seemed to be you could expect return to previous performance levels(in strength anyway) in about 12 weeks or so of proper training and diet.. Almost regardless of how long you have been off. Obviously there are exceptions and extremes that probably don't play out that way, but this has also been about my experience of on-and-off again body building and strength training for the past 15 years. Often the nervous system recovers too fast in my experience. One can ramp up work effort way faster than the muscles and tendons are prepared for, particularly stabilizing components, resulting in strains and pains. Sticking to a ramp up plan is, IMHO, almost as hard as quitting smoking but crucial.
