First, the battle calls up 3 of the same exact monster (which was always weird cause there are 3 different targets in battle with different stats)
Well, I think the following lines change the stats of the arms:
6F03600171A903126020117842806010901260201380418061102790126020136041806110279012602013E0428060009012602013C0428060009072E50372
AE03600271E503126020117842806014901260201380418061401F901260201360418061401F9012602013E0428060009012602013C0428060009072E5039173
In the first one there's 1027 (10000) which is one of the arm's HP. And in the second one there 401F (8000) which is the second arm's HP. So I'm guessing those two segments are altering the original stats of the monster when it loads the same one in 3 times.
This would work the same way as with Bizarro Sephiroth too.
So, if there is an equation that changes Bizarro's and Safer's HP based on using KNights of the Round and being level 99 and all that stuff (like that rumor) then I believe it's modified like this is a segment.
