Understanding the SRN view in the matchup card
SRN is the numeric breakdown view that scores a matchup using 6 factors. This guide explains what each row means and how to read the total.
On the Games page, each matchup card has two views you can toggle between: GAME and SRN. This blog focuses on the SRN view.
1What SRN is doing
SRN is a points-based model. Each factor adds or subtracts points for each team. Positive numbers help that team. Negative numbers hurt that team.
At the bottom, the Total is the sum of all 6 factors. If the home total is higher than the away total, SRN is leaning toward the home team.
2Factor-by-factor explanation
NET RATING
Season-long strength based on offensive rating minus defensive rating. Teams with a better net rating get a positive edge.
Net Rating = avg_offensive_rating − avg_defensive_rating
avg_offensive_rating = (points_scored / possessions) × 100 per game
avg_defensive_rating = (points_allowed / possessions) × 100 per game
INJURY IMPACT (Active Net)
The net rating lost due to players who are listed as Out or Doubtful. More missing impact means a bigger negative number.
Injury Impact = −SUM(avg_net_rating) for all players with status 'Out' or 'Doubtful'
RECENT FORM (Last 10 Net)
Net rating over the last 10 completed games. This helps catch hot streaks and cold stretches.
Recent Form = AVG(net_rating) from game_possessions for the team's last 10 completed games before the current date
HOME COURT BONUS
A standard home advantage. The home team gets a positive number and the away team gets a negative number.
Home team: Home Court Bonus = +3.0 Away team: Home Court Bonus = −3.0
H2H AVG MARGIN
Average point margin in head-to-head games this season. Winning prior matchups by more points increases the edge.
H2H Avg Margin = SUM(margin_from_perspective) / number_of_H2H_games game_margin = home_score − away_score
REST DAYS
Rest and fatigue. Teams with more rest can get a small boost.
Rest Days = today's date − date of team's most recent completed game
