It really is wild. I don't know how your recovery is going, but for anyone worried about this kind of thibg, I will say, that the body does seem to have some kind of memory for prior use snd development generally. For those of us who have worked out moderately to intensely only to suffer an injury or life getting in the way of maintaining consistent practice at the same level, you will find that when you return to working out, you tend to return to fairly close to your prior peak in far less time than it took to get there. Similar to how muscle memory can lead to very quick progression back to your prior level of skill in something that you haven't done in years.

You won't be back to your prior peak, but you'll close 70-90% of the gap shockingly quick.

EDIT: One thing to look out for in situations like GP though, in which development becomes lopsided, is your body will develop lopsided compensation for the disaprity. A lot of physiotherapy often involves learning to force your body to not engage in these compensatory measures so that the diminished or injured part of your body can rebuild its strength and stability correctly.
