So far the underdog is almost exactly as likely to pull and upset in a Value Add Basketball Game as they are in real college basketball games.
To determine the favorite in a game take the rating of one team and subtract from the rating of the other team (so if one team is a +7 and the opponent is a -3 rating above the cards, then the first team is a 10-point favorite).
We play most games on a neutral site, but if you choose to make one team the home team, the adjust the point spread by 3 points in their favor and allow that team to change any die roll from 36 to 66 and vice versa. This recreates the average 2 to 3 more missed or false foul calls that go in the home teams advantage per actual game (in fact the home team might get 7 missed calls in their favor and the visiting team get 4 in their favor, but we just make it average 3 and 0 for the. Same effect).
In 21 of our 307 games played to date teams had the same rating, so in those games there is no favorite. The following table breaks down the results to date based on if a team is favored by 1 to 6 points, by 7 to 9 points or by double digits:

In 48 games one team was favored by 7-9 points, which means www.kenpom.com would project the favorites would win 77% to go 37-11 and ... that is an exact. The Value Add favorites have gone exactly 37-11 in those games.
Finally in 89 Value Add Basketball Games one team has been favored by double digits - an average 14.6 point favorite, and in those games www.kenpom.com would predict the favorites would win 90% of their games to go 80-9 - but in fact there have been for more upsets than expected in those games to leave favorites 76-13.

The 13 games in which a team pulled a double digit upset follow. This could have been due to a great run of dice rolls that will likely even out if the teams play a few more games, or because we underestimated or overestimated one of the teams.
However, with the Colorado 2021, Auburn 2019 and Michigan State 2009 teams all pulling multiple double digit upsets and the 2006 Florida Gators being the victim multiple times, we tweak their rankings and see how their future games play out.
