"PPM" Progressive Performance Metric is a new way to measure skill level
I have created a new way to conduct chess tournament events. Using ratings awarded from rapid matches played on chess.com I have created a new metric: "Performance Progression Metric" or "PPM"
1. **Calculate the "start" rating for each event:**
Start = (Rating1 + Rating2 + Rating3 + Rating4 + Rating5 + Rating6 + Rating7) / 7
2. **Calculate the "current" rating for each event:**
Current = (RatingCurrent + Start - Rating7) / 7
3. **Calculate the "points" for each event:**
Points = Current - Start
Where:
- **Rating1** through **Rating7** are the ratings from the seven previous events.
- **RatingCurrent** is the rating you received after the current event.
- **Start** is the average of the last seven ratings (including RatingCurrent).
- **Current** is the average of the current rating and the last six previous ratings.
- **Points** is the difference between the current average rating and the start average rating.
I use the resulting 'Points" to determine winners in my events held on 4teamchess.com I invite your input and evaluations in regard to the concept.
