I'm assuming this is assuming there's a big skill asymmetry between me and the other person. If so, I deal with whatever they throw at me until the variability in their throws starts to tighten up. At that point, I think they're ready for feedback.
That said, normally the feedback (for a new passer, anyway) is "okay, good, let's change the count."
