Upsets & giant-killers

Measured by pre-match Elo gap, so "upset" means the ratings truly disagreed — not just seedings. Players with fewer than 20 career matches at the time are excluded (their ratings are still provisional).

Methodology

An upset is a win by the player with the lower pre-match Elo; the gap is the rating difference at that moment. Matches where either player had fewer than 20 prior career matches are excluded, since early ratings are provisional. Giant-kills count career wins over opponents rated 100+ Elo higher; underdog records count all matches entered as the lower-rated player (minimum 80).
