Explanation - Strength of Schedule Ratings

Purpose:

• To determine court difficulty in relation to the rest of the league.
• To use as part of a universal league ranking system.

Baseline:

• Players are given a 1 to 10 rating (10 best) at the beginning of the session.
• The ratings are used in determining a court's rating.
• The rating can be adjusted during the session.
• If adjusted, only court ratings going forward are affected.

Court Ratings:

• Each court is assigned a point value between 4 and 40.
• The court rating is typically the sum of the 4 players' ratings.
  • Exception (4-player court): If there is a lone player with a rating at least 1 point lower than the third best player, then that player's value becomes the same as the highest rated on the court - adjusts for difficulty winning with weaker player.
  • Exception (5-player court): The five ratings are totaled and the sum is divided by 5 and then multipled by 4 & rounded to determine the court's rating value.
  • Exception (5-player court): If either 1 or 2 player's ratings are lower than the third best player, then one of those player's values becomes the same as the highest rated on the court.

Calculating "adjusted rank":

• Represent winning percentage as 0 to 100 number.
• Multiply that number times the average court rating to get point total.
• Highest point total is first.
