I suggest using a formula like this: When using the drill helper, make drills holes 1/3 or 1/4 of their size, but no smaller than 30mil. I can easily drill 30mil holes without any special helpers and 30mil is large enough for any etching technique. On the other hand I do have problems centering drills for larger mounting holes. A 30mil hole in the copper is too small to have any mechanical effect on a large drill bit, so it would need to be proportionally larger for larger holes.
