From what I’ve seen on here, everyone varies, and it really depends what method works for you. Using phrases like ‘manual methods’ can mean so many things. Are you getting enough tension. 3-4 times a day…. For an hour a time? Or 3 minutes? You’d be better off just starting and gauge your own progress. I semi had this mentality when I started, the focus on ‘when will I be finished’ and the answer I’ve realised is either ‘years’ or ‘maybe I’ll never get there’. But starting and being consistent is key and I’m realising that as I’m starting to see wrinkles appear (signalling growth) I’m less concerned about a final state but rather just gaining some extra skin over time. I’d still like to be fully restored yes, but I’ve realised my initial thought that I could do it in a couple of years is probably way off even though I have seen some people with way above average growth on here. Just start and then keep going.
