I'd have some questions on how WHR is currently implemented that are not answered in the WHR paper
1. Are teams rated by averaging their WHR first and applying the exponential function afterwards or the other way round?
2. Are FFAs predicted by probabilities proportional to the teams' exp(WHR) or proportional to an average of a team's win probabilities against all other teams? The latter would also make sense according to an earlier calculation
3. Is the visible WHR deviation currently measured by variance or standard deviation?
4. Is the rating variability w = sqrt(14/day) Elo or a different number?
From the current results of WHR, I guess the answer is (1st, 2nd, 1st, ?) and should be (1st, 2nd, 2nd, ?).
