Well, it is still a guideline so it may be broken on practice. But speaking of freedom of choosing a pattern, most people only do (12)(34)(124) or (34)(12)(134) because of how exploitable it is for SR hence seldomly using other variation you just wrote. Also (12)(24)(124) is already a chordglut, not jumptrill anymore lul.

From then till now I have no problems in trying it and yet I saw most to everyone can do it perfectly to frequently in mapping.
Not only because it's now common that makes everyone can stick it with it in every maps but also for some reasons
But first, jumptrill with hand
  
  
  
  
  
  
Thus the opposites
Not to mention other possibilities as
  
  
And don't forget, 4K is not the only keymode have jumptrill
And why you need an extra note?
First in musical logic, if the bass continuously and have no changes in the volume, you can stick with 2 notes jumptrills for challenge and specific the difficulty of the map, and second is the cymbal after it, and yes it's common in most songs, making it 2 notes and classify it being the same with the bass/snare next to it is quite absurd because, kick/snare already 2 notes while cymbal + kick/snare should have higher amount of notes, when normal kick/snare regularly with jumptrill of 2 notes.
I would say it's more of the song itself, if it sounds lighter and you put the same jumptrill wouldn't make senses, meanwhile if its building up stronger and you delete a note before it would make any senses either, it lost the purpose of it, and thus, for consists between parts with that same kind of sounds. However, it's being more on the mapper's judgment of his/her's map as well, restricting something that already happens over the years would be pretty absurd since literally nobody to a real small amount of people did complains to it, over than that, I have never seen other having trauma from passing it during qualified section and yet I user it pretty common, even    (so does 7K).
Mapping it in a freedom way, let the mapper choose what is the best for the map, but yet needs to be reasoning for it, as I mentioned above, so this guideline is quite useless imo.
And, I think I will post some opinions as well when I got the time
And yea the wording is kind of generalizing all the keymodes here, as higher keymodes tend to have these kind of patterns but not have them minijacked. I think it should be stated that this guideline only considers 4K since it's a pretty common keymode.
