Fun Decreasing After Hole Completion.

Hey y’all. I’m doing an impossible difficult play through, and I noticed that after my golfers finish some hole later into my course, they instantly lose a lot of fun, even if nothing bad has happened to them. Now I haven’t looked into it extensively, but I’m guessing that Sims that are above par (on the whole course, or just the whole?) automatically lose some fun. I’m wondering if anybody here knows how exactly this mechanic works. Is it on a hole-by-hole basis, or how above or below par they are for the whole course? Does it automatically scale the further along the course the sim is?

Furthermore, is there a way to counteract this effectively? Should I be designing my holes so the best get birdies/eagles, and the rest get par? As opposed to par and above par? Or do I innevitably have to add in some “breather” holes to get sim’s back towards par?

Thanks!
