It's both, or all 3.
Further south the worms are more resistant, so usually the dosage is higher & more frequent, but not always depends on the management & cullfactors.
Further north the worms (for us) are not so bad, so we dose at 1cc/50#, less frequently. We also rotational graze, breed for resistance, & get a good solid freeze most of the winter.
If you post where you are located I'm sure someone from your area can give you what is working for them.
I would not lessen the dose just because you aren't targeting stomach worms, but instead give an appropriate dose for de-worming and it will take care of the lice. I use Permectrin poured down the spine when I'm targeting only lice during winter.
