NHSDLC National Rankings System
All debaters in the league will be ranked based upon their competitive success throughout the regular season and National Championship. Rankings are updated every several weeks.
Effective for the 2014-2015 season, the National Rankings will consider both preliminary and elimination round performance. Students will be ranked according to a total score that combines their preliminary round points and their elimination round points.
The formula for determining a student's total number of ranking points is:
PW=Preliminary Round Wins
PL=Preliminary Round Losses
EW=Elimination Round Wins
EL=Elimination Round Losses
N=Total Number of Students at the Tournament Attended
TA=Tournament Diversity Adjustment; TA=1+((NS*.25)+(NP*3)/100); maximum value=1.25
NS=Number of Schools at the Tournament Attended
NP=Number of Provinces, Municipalities, Special Autonomous Regions, and Ethnic Autonomous Regions Represented at the Tournament Attended. Province of origin is determined by the location of each team's school.
EC=Elimination Round Co-Efficient
At all regional, national invitational, and national championship tournaments, debaters will receive four (4) points for each preliminary round win and one (1) point for each preliminary round loss. Rounds won on a bye are considered wins, and rounds lost on a forfeit are considered losses for the purposes of rankings.
Students will receive eight (8) points for each elimination round win and two (2) points for each elimination round loss. In addition to these points, elimination round participants will receive additional points for reaching elimination rounds, depending on the type of tournament and the level of elimination round that they reach.
The following are Elimination Round Coefficients for Regional Tournaments:
Double-Octofinals (Top 32): 0.10
Octofinals (Top 16): 0.15
Quarterfinals (Top 8): 0.25
Semifinals (Top 4): 0.35
Finals (Runner-Up): 0.45
The following are Elimination Round Coefficients for National Invitational Tournaments:
Triple-Octofinals (Top 64): 0.10
Double-Octofinals (Top 32): 0.20
Octofinals (Top 16): 0.30
Quarterfinals (Top 8): 0.40
Semifinals (Top 4): 0.50
Finals (Runner-Up): 0.60
The following are Elimination Round Coefficients for National Championship Tournaments:
Triple-Octofinals (Top 64): 0.175
Double-Octofinals (Top 32): 0.35
Octofinals (Top 16): 0.45
Quarterfinals (Top 8): 0.55
Semifinals (Top 4): 0.65
Finals (Runner-Up): 0.75
Tournament Diversity Adjustment:
Tournaments with substantial representation from outside the host school and host province are more likely to have difficult competition pools. Therefore, the NHSDLC adds a slight adjustment value to tournaments with high diversity of schools and provinces of origin. The Tournament Diversity Adjustment (TDA) is designed to reflect the added difficulty of these tournaments. The TDA has a maximum value of 1.25 and minimum value of 1.00. The TDA is calculated by: (([Total number of attending schools]*.25)+([Number of Provinces Represented]*3)/100)+1.
Our national ranking system is cumulative within one year, but resets at the beginning of each new academic year. The academic year begins on September 1st and ends on August 30th of each year.
A student named Ann went to a regional tournament with 140 debaters attending, representing 8 schools and 2 provinces. The tournament advances to Double-Octofinals (Top 32). Ann and her teammate won 3 of their 4 preliminary rounds, and were defeated in the Quarterfinal Round. We would apply the X=((PW*4)+(PL*1))+((EW*8+EL*2))+((N*TA)*EC)) formula to determine her points.
Therefore, Ann and her teammate would have a total point value of 60.7.
