### ABOUT

Running since early in the 2010/11 season, BritHoops.com has been dedicated to compliling stats from the British Basketball League. At that time stats from the BBL were quite hard to come by, so we aimed to create a space where fans can access up to date stats easily, hopefully presented in a clear and concise way.

#### Stats

We compile all our stats from the box scores published on bbl.org.uk. On this page you can find a glossary for all the abbreviations we use for stats along with further explanation relating to some of the more complicated 'advanced' stats we have on the site.

#### Advanced

For the non-traditional, non-box score 'advanced' stats featured on BritHoops.com we primarily use the methods detailed on the highly esteemed US site Basketball-Reference.com . Further details below.

###### Offensive / Defensive Ratings (ORTG / DRTG)

Team Offensive / Defensive Ratings are a measure of how efficient a team's offense and defense are by examining points scored/allowed per possession. The formula we are using for estimating the number of team possessions is:

`0.5 * ((TmFGA + 0.4 * TmFTA - 1.07 * (TmOREB / (TmOREB + OppDREB)) * (TmFGA - TmFGM) + TmTOS) + (OppFGA + 0.4 * OppFTA - 1.07 * (OppOREB / (OppOREB + TmDREB)) * (OppFGA - OppFGM) + OppTOS))`

As Basketball-Reference state: "This formula estimates possessions based on both the team's statistics and their opponent's statistics, then averages them to provide a more stable estimate."

Dividing a team's points (both scored and allowed) by number of possessions gives a Points Per Possession (or PPP) figure. For Offensive and Defensive ratings we just multiply this by 100 to give a slightly more palatable number. As such Offensive and Defensive Ratings represent points scored/allowed per 100 possessions.

Individual offensive and defensive ratings try to do exactly the same thing, e.g. estimate the points scored/allowed per possession when an individual is on court. The formula for this is *slightly* more complicated though and frankly we can't be bothered to write it all out here.

You can check out the method we use for calculating our individual offensive/defensive ratings on Basketball-Reference right here though.

###### Usage Percentage (USG%)

Usage Percentage is an estimate of the percentage of team's plays a player uses while they were on the floor. The formula (which tries to take into account field goal attempts, free throw attempts and turnovers committed) is:

`100 * ((FGA + 0.44 * FTA + TOS) * (TmMIN / 5)) / (MIN * (TmFGA + 0.44 * TmFTA + TmTOS))`

###### Effective Field Goal Percentage (eFG%)

Effective Field Goal Percentage adjusts shooting percentage to reflect that a 3-point field goal is worth one more point that a 2-point field goal. The formula for this is:

`(FGM + 0.5 * 3PM) / FGA`

###### True Shooting Percentage (TS%)

True Shooting Percentage is another measure of shooting efficiency and takes into account field-goals, 3-point field goals and free throw shooting. To calculate this we use:

`PTS / 2 * (FGA + 0.44 * FTA)`

###### Rebounding Percentage (OR% / DR% / TR%)

Offensive, Defensive and Total Rebound Percentage is an estimate of the percentage of available rebounds a player (or team) grabs. For individual OR% we use the formula:

`100 * (OREB * (TmMIN / 5)) / (MIN * (TmOREB + OppDREB))`

For individual DR% we use:

`100 * (DREB * (TmMIN / 5)) / (MIN * (TmDREB + OppOREB))`

And for TR% we use:

`100 * (TREB * (TmMIN / 5)) / (MIN * (TmTREB + OppTREB))`

For team rebounding percentages we just look at a team's and their opposition's rebounding numbers. So for team OR%:

`TmOREB / (TmOREB + OppDREB)`

For team DR%:

`TmDREB / (TmDREB + OppOREB)`

And then for overall team TR%:

`(OR% + DR%) / 2`

###### Assist Percentage (AST%)

Assist Percentage is an estimate of the percentage of a team's field goals a player assists whilst on the court. The formula is:

`100 * AST / (((MIN / (TmMIN / 5)) * TmFGM) - FGM)`

###### Turnover Percentage (TO%)

Turnover Percentage is an estimate of the number of turnovers a player commits per 100 plays. To work it out we use:

`100 * TOS / (FGA + 0.44 * FTA + TOS)`

###### Steal Percentage (STL%)

Steal Percentage is an estimate of the percentage of opponent possessions that end with a steal by a player when on the court. The formula we use is:

`100 * (STL * (TmMIN / 5)) / (MIN * OppPOSS)`

###### Block Percentage (BLK%)

Block Percentage is an estimate of the percentage of opponent 2-point field goal attempts are blocked by a player when on the court. The formula is:

`100 * (BLK * (TmMIN / 5)) / (MIN * (OppFGA - Opp3PA))`
