SECTION 18 — RATINGS, LEADERS AND CALCULATIONS

1. Annual Leaders for CFL statistical categories are determined by the following guidelines:
   • Rushing average leaders are based on a minimum of 100 attempts for a season.
   • Pass Reception average leaders are based on a minimum of 40 receptions for a season.
   • Punting Average leaders are based on a minimum of 60 for a season. Kickoff average leader minimum is 30 per season.
   • Completion % and Pass Efficiency leaders based on a minimum of 300 passes for a season.
   • Quarterback Rating (QUAR) leaders based on a minimum of 60 possessions for a season.
   • Field Goal % leaders are based on a minimum of 30 attempts in a season.

2. 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:

• All CFL Stats Crews will record Scoring Drives and include this information in the statistical play-by-play reports at the end of each drive. The drive information must include the number of plays, the yardage gained, a description of the scoring play and the total time of the drive; all drive information will be compiled into a Drive Chart Summary Report.
• A Drive starts at the Line of Scrimmage of Team A’s first play of a series, and ends with either a scoring play or loss of possession. Penalty plays and kicks are both counted when determining the number of plays in a drive. However, a Convert attempt is not counted.
• Game statistics will include other analytical information including 2nd Down Conversions, Red Zone Offence (defined as the results of any drive with at least one play run from the opponent’s 20-yard line and closer), total number of plays, scoring by quarter etc. All CFL Stats Crews will also record other relevant game-related information including: weather and field conditions, wind and temperature, attendance, Coin Toss results, game duration, a record of Coaches’ Challenges, and the names of the Officiating Crew. Play- by-play records will record other relevant events such as Timeouts and unusual delays.

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.
