I just go with Fender's suggestions. Works for me.
Bass Side 5/64"(2 mm)
Treble Side 4/64" (1.6 mm)
On a 7.25" radius.
It depends of the fretwire and the subtle twists of a neck (none are perfect) I like to start with string height at nut, then level the string to fretboard to bridge (bridge height). Then I add relief, then start the string height at the 17th fret at 4/64. I lower if a taller fret and and able to with my pick attack without getting buzz up the fretboard.
