Fast critique has its place, but it can reward quick opinions over careful reading. Near the end of the year, I like reviews that move a little slower.
A slower review gives the designer time to explain constraints. It gives the team time to understand the user problem before reacting to the surface.
I have found that the best feedback often comes after a pause. Someone notices a hidden dependency, a missing state, or a simpler path that was not obvious at first glance.
Slower does not mean less rigorous. It means the review is designed to produce better decisions, not just more comments.
