The method outlined in frets.com works for mandolin, banjo, guitar, whatever.

I've found the guidelines given by Mr. Ford to be a bit conservative wrt string height ... on the A & E courses especially.
But that's just my preference and my mandolin. Remember ... you can always cut deeper, but you can't cut shallower.
