I did a little work after comparing to our actual scouting data, and it seemed while teams like ours had a reasonably accurate OPR, it's really easy for one's OPR to balloon this year, so in a regional ranking sense it's less accurate overall. Technical fouls and fouls aren't removed from the data. Teams that have a playstyle that draws fouls, or just played worse opponents, get an advantage in OPR.
At WPI, a few teams happened to have their non-functional matches paired with other good teams, and OPR doesn't really know how to separate that out. Additionally, defense is huge this year, making this game less separable than other games. So while our average contribution to a match might be close to our OPR, other teams were a ways off in one direction or the other due to scheduling oddities or hella technical fouls.
