AeroPod, PowerPod and Newton

Hi Everyone - I've been tracking my w/kg progress since my first ride with my iBike (see below if you're interested). I know best practice is to use a benchmark route to track progress. I'm getting into that habit now, but I'm wondering if there's a way to compare w/kg for dissimilar rides by using distance to "normalize" the w/kg measure. For example, I'd like to know if 2 w/kg over 30 mi is better/worse than 3 w/kg over 20 mi. I'm thinking there might be a math equation? Absurd? Possible?
