Muscle memory is creepy

I’ve been practicing country licks and flatpicking on acoustic lately and I hadn’t played shred stuff in a few months. So this morning I was in a Yngwie mood and I started playing about the first half of “Far Beyond the Sun” and I nailed all the fast sections perfectly, strict DWPS. Is this what people mean by muscle memory?

Yup
And also regular memory, provided you didn’t have to re teach it to yourself.

Sob, I wish my technique was low maintenance like this, but particularly with TWPS it seems I lose it very fast when I don’t practice it!
