2020 is obviously very different. It is hard to predict when or if I will be able to produce reasonable ratings using my methods, so compared to prior seasons there will be less reference material here. I will still provide the composite rankings based upon Dr Massey's compilation and the occaisional bit of commentary.
For now the reference material only includes the schedules for the 97 1A and 1AA teams included in Dr Massey's consolidated schedule.

Reference Ratings
With some patching and grimacing I can produce ISOV and ISR reports. Teams that have played no games are not rated, and with the field as disconnected as it is the results are suspect to say the very least.
- ISR
- Boyd Nation's Iterative Strength Rating
- ISOV2
- Improved ISOV
Scoring data adjusted by opponents' ISOV2 strengthOften people who are not familiar with the nature and limitations of statistical methods tend to expect too much of the rating system. Ratings provide merely a comparison of performances, no more and no less. The measurement of the performance of an individual is always made relative to the performance of his competitors and both the performance of the player and of his opponents are subject to much the same random fluctuations. The measurement of the rating of an individual might well be compared with the measurement of the position of a cork bobbing up and down on the surface of agitated water with a yard stick tied to a rope and which is swaying in the wind.Arpad Elo in Chess Life, 1962 In theory, there is no difference between theory and practice; In practice, there is. — Chuck Reid
