The set introduced the concept of "Nationals-minus" difficulty, which it described as "noticeably harder than tournaments such as ACF Regionals and Penn Bowl, but not as hard as ACF Nationals or last year’s George Oppen."
Evaluation of difficulty
Because many teams played both "stanford housewrite" and 2016 ACF Nationals two months later with the exact same lineups, the concept of "nats-minus" difficulty can be evaluated by directly comparing metrics:
|"stanford housewrite"||2016 ACF Nationals|
* DTG = dead tossups per game involving this team, incorporating both their skill and that of their total opponents
Every team had a higher PPB at Stanford Housewrite than ACF Nationals, and those who had common lineups had a higher PPB still at ACF Regionals, suggesting that the "between Regionals and Nationals" difficulty was achieved in the bonus questions.
Four of the seven teams experienced more dead tossups at Stanford Housewrite than at Nationals, suggesting that tossups were less well-calibrated. A lack of buzzpoint data at both tournaments and the non-use of powers at Nationals precludes exploring issues such as how deep tossups went on average before being answered.
The Oklahoma mirror was only 7 rounds and was forced to change formats after its fifth round when two of the eight total players spread across its five teams had to leave. The remaining players were consolidated into "Oklahoma" and "Other Dudes" for the last two rounds".
