1 over 3 under is by far the best method. At least never put more coils there. You can get by with just 1,5 loops but it's more difficult to string, 1-3 method is super easy and quick and never loses the tune.

Tuners have to be really shitty to affect tuning stability...more like bad tuners make it very hard to GET it in tune but even the worst ones stay in tune well enough...just the getting there can be very hard.
