If you come across terms or abbreviations you don't understand, or a certain usage or convention does not seem proper, please report to me with your concern and interpretation. Information will be adjusted or convention used will be documented. Your assistance in making CFLdb Statistics more accessible is appreciated.
I strive to present the most accurate data available on CFLdb Statistics. The farther back in time you go, the harder this is.
Game scores have been verified against multiple sources, all obvious errors discovered through compilation have been corrected and are believed to be 100% accurate. However, there are some discrepancies in the compiled data compared to CFL published standings. These differences are (+ indicates CFLdb compiled totals are above CFL listed totals, - indicates CFLdb compiled totals are below CFL listed totals):
If you can find the error in the data for these issues, please let me know.
Pre-season game results may not be accurate or complete prior to 1970, which in turn affects the compilation of pre-season records. If you can help complete this information, please contact me.
Attendance numbers are based on best available information available. In cases where exact figures are not available, I attempt to estimate the value by deriving the amount from season totals or media estimates. In early years, exact attendance was often not reported, so estimates are taken from media reports. Where no actual attendance is available or estimates are able to made, the attendance figure will not be available. Games without attendance figures are not included in any compilation calculations.
There are two sellout designations: announced sellouts and sellouts. Announced sellouts are a manual flag indicating the team/media announced either prior or after the game it was a sellout crowd. Teams will often report a game is sold out when only single game tickets are available (no side-by-side seats available). When doing so, some teams report the actual number of tickets distributed less than capacity while others will report the stadium capacity as the announced attendance. It is possible, therefore, for an announced sellout crowd to be less than known or maximum capacity of the stadium.
Sellouts are calculated based on 100% or greater than stadium capacity. CFLdb sellout numbers will differ from team claims when they report tickets distributed less than capacity for sellout crowds, however, announced sellout counts should match team claims.
An announced sellout may not be a technical sellout, but a sellout is always an announced sellout. In the near future, tracking of both announced sellouts as well as sellouts will be added to CFLdb Statistics.
Broadcast ratings are the sum of all broadcaster ratings for a game (Canadian broadcasters only, I have no US broadcaster numbers) averaged over the number of games available. For instance, when available, the RDS and TSN ratings numbers will be summed, and that instance added to the sum and divided by the number of games. Sometimes ratings are provided as a RDS/TSN or CBC/CTV/RC total and a breakdown is not available. In these instances, the total is recorded under one broadcaster. Ratings can be overnight ratings or the weekly ratings, whatever is available and sourced through the media.
Game times are displayed in the web visitor's time zone and local time of the stadium location when known. If the exact game time is not known, only the date is shown. Weather data is based off the game time, and is displayed in local time. If the game time is unknown, weather data will not be available. If you have game time information for a season, please pass the information along to help me fill in this information. Weather data is based on the closest Environment Canada weather station and so may not reflect the actual conditions at the stadium (especially for more localized events like thunderstorms).
Coaching terms are listed as the day employment was announced and terminated, when known. If those dates are not known, but season(s) coached are known, then a start date of Jan. 1 and end date of Dec. 31 of the start and ending years are used if they coached the complete year. This applies to older coaching terms, usually prior to 1960. If a coach was terminated immediately after a game (as reported in news articles) prior to midnight, the next day is used as the termination date to give the coach credit for the last game coached. Interim coaches are given credit for all games they appear on the sidelines in the cases of firings, medical emergencies or other factors that caused a head coach to miss a game. This may affect the compilation of coaching records. I do not know the policy of the CFL for accrediting wins and losses to coaches who did not appear on the sidelines. For example, Don Matthews is listed by the CFL to have 231 career wins, while my compilation shows 230 wins.
Only franchises that have seen the field are listed. Phantom franchises such as the conditional 1980's Halifax/Atlantic franchise or the 1993 San Antonio franchise are not considered to have existed.
The CFL's term for franchises is referred to as teams on CFLdb Statistics and is the primary organization method. For instance, the CFL's convention is all Montreal teams from the 1946 Montreal Alouettes through the Concordes to the present day Alouettes are one and the same franchise, in my vernacular, a single team. CFLdb Statistics also breaks down history by franchise, which is tied to the awarding of a franchise and survives transfers from city to city. For example, I list Baltimore and the current Alouettes as the same franchise. This allows record comparisons by team, franchise and city (for instance, all Montreal teams, even those prior to the 1946 Alouettes).
Ownership groups, membership, percentage of ownership, and dates are taken from media reports and information in CFL Facts, Figures and Records. When information is available to derive membership and percentages from known information, I attempt to do so in a neutral manner.
Stadium information has been compiled from media reports, CFL Facts, Figures and Records and other sources. The last capacity known is used in calculations until a known capacity change is available. This may affect figures like percentage of capacity.
If you have an issue with any of the conventions, estimates and choices I have made, please contact me, explain the issue I have created and provide a suggestion for correcting it. I also appreciate any data that can help fill in my gaps or provide new sections of information. Your assistance will be credited on the sources page or contributor page as you specify. See the contribute page for more information on current initiatives and how you can help.
