How the ratings work
- ATC Rating
- On the same scale as a 500 score. It's the average of your best 5 Card Ratings from the last 18 months. You need 5 rated cards to be ranked. A year's Rating is your ATC Rating at the end of that season (the 18 months to 31 Dec; the current year uses 30 Sep until 31 Dec).
- 80-Shot Rating
- The same as the ATC Rating but for 800-point (80-shot) matches like Games Cup days and 800 aggregates. Best 5 in the last 18 months.
- Best 10 Avg
- The average of your best 10 totals over 18 months (EIC and NTI cards for EIC, 800-point cards for 80-shot). The current year runs 1 Jul last year to today; past years run 1 Jul to 31 Dec. Field beaten, consistency and X counts use the same 10 cards. The change compares it with the year before.
- Stage Averages
- The average of your best 10 scores and their X count in each stage over the same 18 months, kept separate for EIC (EIC, NTI and same-length President’s stages) and 80-shot.
- Recent Form
- The average of your last 5 Card Ratings, next to your ATC Rating.
- Field Rating
- How strong the match was, on the same scale as a 500 score. It's the average of the top 10 entrants' prior-year EIC averages, set before anyone shoots. A match needs at least 5 rated entrants to get one.
- Card Rating
- Your score adjusted for the day. It's your score plus the field's prior-year average, minus what those top 10 shooters actually averaged that day. A tough day adds points and an easy day takes some away. It tops out at 500.
- Consistency (±)
- How much your scores swing from match to match. It's the standard deviation of your best 10 totals over 18 months, so lower is better. ±5 means your scores usually land within about 5 points of your average.
- Beat
- The average share of the field you finished ahead of in your best 10 cards over 18 months. 94% means you beat about 94% of the other shooters each time. A win is 100%.
- Rival
- A shooter at your level (same Distinguished status, a Perry regular like you, and an ATC Rating within 5 points of yours) you've shot at least 10 matches with, whose scores are closest to yours.
