But there is a potential problem: I don't know how precisely the experimentalists have pegged these values either for current years (when direct
measurements are possible) or in past years (when direct measurments likely weren't done) It may be the
uncertainty bounds from in experiments are rather large giving modelers quite a bit of leeway.
Probably if you did something besides ordering the top 30 by correlation (remember there is
measurement error so the ordering is not accurate), you could get rid of bias, and end up with a measure that provides
uncertainty bounds with it.
