Thanks to @Day for getting friends together and taking her own time to gather this data, and for writing it up in this thread: Guide to all PIMD Parties (hyperlinked). In this thread, I've calculated how much damage you need to deal to a party per hour, as that's the best way I could think of to put a number on their difficulty. Stars ratings are also visible beneath the parties to indicate their difficulties. Difficulty is measured in DPH or Damage per hour, which is calculated by dividing their Hit Points by their duration (in hours). Star⭐= ~10,000 damage per hour Twinkle ✨ = ~5,000 damage per hour Art Skool Fake Art 101 (Easy) Damage per hour (dph) = 18,500 ⭐⭐ DIY Tattoo (Easy) DPH: 29,500 ⭐⭐⭐ Factory Art (Easy) DPH: 17,500 ⭐✨ Art Starzzz (Easy) DPH: 24250 ⭐⭐✨ Hype Machine (Easy) DPH: 23,125 ⭐⭐✨ Back Alley Debut (Easy) DPH: 40,200 ⭐⭐⭐⭐ Pizza Pop (Art) DPH: 15,833 ⭐✨ The Bro Code Prank Primer DPH: 46,500 ⭐⭐⭐⭐✨ Frisbee Follies DPH: 20,000 ⭐⭐ All Roads Lead to Beer DPH: 26,500 ⭐⭐✨ Restless Keg Syndrome DPH: 33,833 ⭐⭐⭐✨ It’s Brostep, Brah!

I shared this with a friend, @KitCat04 and she said that the thread is too simplistic to show difficulty and that how much Str HP and Int HP a party can also be taken into account when choosing which one to start... That, say, if you have lots of strength builds online, you can go for a more difficult party that is strength-dominant, but would fail one that is more intel-dominant. She also lamented that it would be best if people hit parties that suited their build, but that everyone makes the most money off of dance bars followed by fight, prank and eavesdrop and as such they are incentivized by the game itself to complete parties sluggishly. If your plunder and damage on parties were linked, and they were based on your build, that would give club admins and owners more control over parties and their outcomes. Further testing has to be done but it would be really neat if the devs made things more sensible. More testing into party damage needs to be done to get to the bottom of this.
For FA101 it takes me a little less than half UL to finish a sigh bar. Respectively, I have not tested soloing FA101.
