I'm just sort of thinking aloud here. I really enjoy Pythagorean W-L% because it tends to be surprisingly accurate. Furthermore you can use the same equation in 1889 or 1922 or 1975 or 2010 unlike the nonsense that accompanies linear weights.

Is there something similar out there (or possible) that could be computed for a pitcher given his run support and runs allowed? You could go a step further and adjust for team defense, but I just want to know if there's an empirical way to calculate the base % using only runs
