Yep! I've never owned a guitar that I didn't level and re-radius the frets to some degree. I don't really measure, it's more a by feel thing but I'd guess 9" near the nut to 12+" further down the neck. Saddle radius is also important to me. Intonation comes into play, and I intonate my guitars a bit differently than most people, I won't go into that here, but again by ear, as I've never owned a guitar tuner. I don't think there is a magic off the shelf formula, at least not for me.
