Guidelines to resolve ties in medal play (with handicap)

That's what I don't like about using exact handicaps, because that means that a 0.1 difference in the index of two players, in the 9/6/3 holes fraction, might lead to extra strokes assigned.
Explaining that to players is even harder than explaining that ties are resolved by using countback based on a "net score per hole" (it is, gross strokes minus handicap strokes).

I've seen different ways of breaking ties, I like that the lowest gross unties (you reward the better player), but as said before, it's unfair in some broad handicap competitions.
