At rest, you will want your impulse jewel to sit in the pallet fork horns, and yes,..you want it (the pallet fork) to be centered.
That adds insurance that the watch will be “in beat”,..and will start easily within a few winds.
So however you have to move the hairspring/collar group to attain that, is what you are shooting for.
I mark both where the stud sits, and which way the impulse jewel faces..just to be safe.
On a two arm balance, it is the “norm” to have the roller jewel ( impulse pin ) sitting at right angles to the arms.

I can’t trust my memory when I’m working on more than one at a time…
Best,

Randy
