It your crits are going well, each presenter will receive a huge amount of feedback, much of it conflicting (different folks may have different opinions). Some of it may also not be actionable in time (for a deadline for example).

So the idea here is that people give feedback without the expectation that it’s necessarily implemented, or that all of their questions are necessarily answered, hence my comment about not necessarily closing the loop (though it obviously being valuable, when possible).

This is one of the most important differences between crits and reviews.
