Interpretation rating performance

Hi,
I was just looking at the results of the friendly homework and the corresponding rating performance
Do I read it correctly, that with my rating of <2100, I am expected to get 1-1.5 correct for mixed?
I am confused because the average rating is 1933 and average score is 3.24.
Does that mean very high and very low ratings are over-represented? I appreciate that the sample size is too small for a precise read
Thanks!

Aagaard said the performance is calculated by the top 10.
I’m not sure what are the average score of top 10.
However I think the killer homework rating performance is more realistic than the friendly homework.
Maybe it is intentional to make it “friendly”.
