For certain statistics they are calculated by the following guidelines:
Time of Possession:
Credited to a Team whenever it is in possession of the football including kicking plays. After receiving a kick, Team B’s possession starts at the beginning of the next play from scrimmage (unless there is a fumble lost by the returner). The total Time of Possession (Team A’s TOP plus Team B’s TOP) for every CFL game must equal 60 minutes (60:00).
Net punting:
Total punt yards - Opponent return yards - 35 yards per punt single
Pass Efficiency Rating:
Based on four separate indices as a function (divided by) pass attempts: Yards, completions, TD passes and Interceptions
(((Completions/Pass attempts*100))-30)/20 +
(((Passing yards/Pass attempts)-3)*0.25) +
((TDs/Pass attempts)*20) +
(2.375 - (Interceptions/Pass attempts*25))*100/6
QUAR - Quarterback Rating:
Based on 12 separate weighted indices incorporating Pass Efficiency as 40% of the calculation with the following additional team and individual statistics for Quarterbacks while they are in the game (QB of record for a drive):
Factor | Wgt | Description | Sample results or average |
---|---|---|---|
Offensive points | 15% | Points per possession | 2.2 or 33 points on offence for a game |
W-L % as Starter | 10% | W-L percentage | 15-1-1, .912 win % |
Net Offence | 10% | Net yards per possession | 28.0 or 420 yards for a game |
First Downs | 5% | First downs per possession | 1.4 or 21 first downs for a game |
2nd Down Conversions | 5% | Percentage made | 48% (12 for 25 conversions) |
Individual Fumbles | 5% | Fumbles per possession | 0.03 or about one every other game |
Indiv. QB Sacks Taken | 5% | QB Sacks Taken per possession | 0.15 or about 2.25 per game |
Indiv. QB Rushing yards | 5% | Rushing yards per possession | 2.00 or about 30 yards for a game |
Pass Efficiency Rating | 40% | Existing Pass Efficiency indices | Completions, Yards, Ints, TDs per attempt |
Drives and Other Analytical Information:
Game statistics will include the result of all drives where at least one offensive play is run from the opponents' 20-yard line and in. This result is known as Red Zone Offence - and the % success rate is expressed as Touchdowns / Red Zone Opportunities.
