I have been looking at online encounter builders and I have noticed that they add 15XP for each extra player beyond the fourth. Meaning, a 4-person party has a 60 XP encounter budget, a 5-person party a 75 XP budget and so on. This is the same as in the pre-remaster Core Rule Book. But the GM core says that the encounter bidget should change by 20XP for each player after the fourth, leading to 60, 80, 100 and so on.
I just wanted to make sure that I am applying the right rule when building encounters and I want to notify Paizo, just in case this was a typo and it should have been 15 instead.
