Re: 3 month vacation:
studies have shown that the effect on children is 1.5 months of reteaching required; for adults, it is FAR less.
Re: Professional level of skill
CT defined employble as level 1, and level 3 as professional
MoTrav defines employable as level 1 and level 2-3 as professional, with 4+ being expert.
Re max skills:
Int+edu makes 14 levels for "joe normal"... meaning it starts to get full around mid-life. Skill retention is in part based upon practice and in part upon age of learning. If you learned you tae kwon do in your youth, you are likely to retain more of it long term than if you learned it solely as an adult. Learning and knowledge loss both slow with age.
I hardly ever shoot any more (0 practice) but I am just as good on targets as ever on the rare (annual) occasions I do shoot. I seldom program anymore (no time) but I'm better at coding efficiently than when I programmed more (Improved int and/or edu?). Probably never exceeded level 1, and quite possibly still am.
