@Whackadoodle:
Fourth, I suspect we're seeing just how badly wounded Law is, since this was one of the smallest Rooms we've seen. He probably doesn't have the stamina left to make one of the fuck-off-big ones that are (presumably) needed to cut through the hardened CoA of someone like Vergo or Doflamingo.
I would love if that was the case.
The problem is, that we can't tell, since his powers are so… undefined.
@Whackadoodle:
Speaking of Skypeia, that punch came 42 chapters into the arc; this one, of course, is 59 chapters into the arc. It's admittedly a completely arbitrary metric, but if we assume that first connecting punch happens at about the same relative point in the arc each time, Dressrosa will end up being about 91 chapters. As a result, I think it's a reasonable estimate that Dressrosa will run a total of 75-95 chapters. I had previously been guesstimating somewhere around 70-75, but that doesn't feel like enough to wrap up the outstanding flashbacks, Zoro v. Pica, Sabo v. Fujitora, Robin(?) v. Gladius, Kyros v. Diamante, Franky v. Senor Pink, Law(?) v. Trebol, Luffy v. Doffy, and then wrap up the arc.
You forgot about citizens.
I'm guessing we are in more of a Water 7/Enies Lobby length. So between 100 and 110.

Yeah, I remember those now. No instances of Observation though? He may just not be able to use that one.
I dunno, problem with Observation is that unless one figths with enemy using projectiles it is incredibly hard to tell when it's being used.
