Hi Sooger, welcome back to the ice!
While I won't be 47 until May (ahem ahem, let's not push things here!!!

), I'll be happy to answer your questions too.
I skated for 7 years as a kid, from ages 7-14. At the time I left, I had passed ISI Freestyle 6, which meant I could do a decent 2toe and 2sal and a flying camel and possibly some kind of flying sit spin. I also skated pairs and some ice dance for 5 of those years, so my practices were divided up between skating alone and with my partner. My partner and I could do a number of lifts and death spirals.
Then I basically did not skate for 30+ years, except maybe on about 6 separate occasions. Each time I would try to "regain" my former skills in one skating session, and each time it got uglier and harder!
When I "came back" almost 2 years ago, I was only skating one day a week for about 4 months. Then I realized I had better get a coach, and that's when things started to change. While I could land my single jumps right away, they were ugly and pathetic. She brought them back quickly. I started practicing 3x a week, for a total of 5 hours.
She didn't want me to do axels, but I was working on them in practice. They were ugly, but I would land maybe 1 in 10. But we were so busy concentrating on getting me to pass my Moves in the Field tests, that it wasn't for about 8 months until I started work on them again. Right after I broke my wrist (standing up on the ice, taking notes), I attended a seminar by Olympic coach Kathy Casey. Since I was in a cast, she didn't want me trying axels; only once arounds. But she drew a diagram of how my takeoff should be, and at the next practice I tried it and landed 7 out of 10!!! What a shock! Now I usually land 9 out of 10, and they are much bigger. Now I am skating 4x a week for a total of about 7 hours a week.
But enough about me. What I think is the best thing to do is to not worry at all about what you used to be able to do. Even though I found that things came back pretty quickly, I also think they came back kind of ugly! Your body is not the same body that it was 10 years ago, no matter how good of shape you are in. It's just different. It's older.
So the best advice I can give is to start back from the beginning, have patience, and train your body to do things all over again, right from the basics. Work on eliminating any bad habits and don't worry about not being able to do something yet. I think we "returning" adults are better off thinking of ourselves in the present (like Icer says). Because when it comes down to it, you should love to skate, you should continue to strive to improve, and you just never know how quickly you will follow one breakthrough with another. There is no right or wrong length of time, and you can't judge yourself by what others do.
Remember that old adage, it's not the destination that is important, it's the journey. I try to enjoy every single stroke of the journey. I hope you will too.
And best of luck with your skating!!!!
