I agree with your statement. I wasn't trying to say the USTA should adopt the ATP/WTA systems, just pointing out that as a general concept, you can very successfully, treat all matches the same regardless of the ranking of the opponent.
And to be honest, I'm not even advocating totally ignoring opponent ranking, just point out that there is likely no statistical justification taking that ranking to 3 significant digits.
