Maybe 'guitarbuilding' are basing(!) the Not For Bass on the basis that Guitar are ballpark 2 / 1.5mm and a Bass ballpark 2.5 / 2mm...
But, i likes @Hellzero simplicity, and savings as well as suiting all radii...
Saddle screws M3 have a 'pitch' of 0.5mm, so half a turn extra per string saddle would add 0.25 of a mm in height.
EDIT: At the bridge... so about half that at the 12th fret...
So Full Turn 0.25 at the 12th.
