#WritersCoffeeClub 8: While editing, what most clearly signals a pacing issue?

A whole lot of things can be indicators: it all depends on context!

"The plot seems to run on rails for a long sequence" in one recent problem child WIP was the outcome of one of my characters being just too passive (that's going back for a major rewrite). "I don't understand why X did Y" often means the background/explanations leading up to it are rushed. And so on.
