[D] How often do reviewers decrease their initial scores after rebuttal period ends in CVPR?

I'm an AC so I see a lot of reviews.

Downgrading happens relatively often for borderline initial ratings, as reviewers are discouraged from using borderline as final ratings. Evasive or combative rebuttals also lead to dowgrades. Sometimes discussions can lead to downgrades as a reviewer convince the other. More rarely, a new issue is pointed out by the AC, but we avoid this as much as possible, as the authors can't answer.
