I wonder, would it be possible to make an elo-based RT ladder based on this? All the necessary data seems to be there.
I guess it is possible. There is indeed a lot of data and I thought of this idea some time ago, but there two issues:
- What would be the practical purpose of such a rating?
- There would be so much criticism from every side about the ranking algorithm, that it would discredit any idea of ranking. (Judging by all the rating discussions of other ladders/QM/etc here)
