Tradeskill FormulasFollow

Have been working to start my toons in various tradeskills (never really cared for doing it before)... I've been trying to research this info, and not having much luck. I'm wanting to know what the formulas are for determining how far you can go in a tradeskill at the present level of the toon. The only one I've been able to find so far is Alchemy at (LVL-24)*5, meaning a level 25 Shaman can only get the tradeskill to 5 before he has to up his level before working on tradeskill again. If anybody knows the basic tradeskill formulas I would appreciate a post here with them all in one area. Working on all of the main skills, brewing, fletching, tinkering, baking, pottery, jewelcraft, tailoring, blacksmithing, etc. Hope someone can help me with this. Going nuts reading all these guides on tradeskills and nothing shows the formula. Everybody have a Happy Thanksgiving as well.
