By my calculations, Fire I with a free Firestarter check is roughly 76 PPS, 250 potency F4 would be 83.33 PPS, 260 potency would be 86.66 PPS. The 250 would be about 9% stronger within the rotation, 260 estimation would be about 13% stronger within the rotation.

I think a F4 X 4, F1 X 1 rotation will probably lead to the highest dummy numbers, at least in terms of raw damage output. I feel like F1 X 2, F4 X 3 will be more practical in mobile fights/parts of a fight, it should in theory only be about a 1.5% average potency loss for the rotation but if you make use of the Firestarter in any meaningful way then it'd make up for it.
