Official Method
20 x ( Adjusted TPPTH + Adjusted BHPTH x Adjusted PPB)
Brief Explanation
The D-values main function is to roughly find the average point per game a team would have against the "average" quizbowl team. This is done by finding the tossup points per tossup heard (TPPTH), bonus points per tossup heard (BHPTH), and points per bonus (PPB). By taking the TPPTH plus the product of BHPTH and PPB, this tells us roughly how many points a team would get per tossup heard, including bonuses. Since there are 20 tossups in a NAQT tournament, it makes natural sense that this figure would be multiplied by 20 to give an estimate for the average number of points per game we would expect a team to get. Other factors such as strength of schedule (SOS) and division question correction (DC) are also taken into consideration, but skipped here to to brevity. These can be found under Additional Sources.
