Interesting stat . . .
While I only give modest weighting to a pitcher's ERA stat (WHIP, frequency, venue, and quality of opponent are more important imho) nevertheless I keep a record of each starter's ERA each day (if a one-inning reliever starts in front of a the main BULK inning pitcher, I use the bulk inning dude's ERA stat)
At the end of the night I tally the wins by the teams with SPs who had a significantly better ERA than his counterpart (disregarding AAA callups or any starters with only 3 starts or less) Usually meaning one SP is about a full run ERA better (like 2.50 vs 3.50 and so on) but it's a subjective call when the numbers are closer, and often I just call it too close and a wash...
But when I have subjectively determined that one SP has a significantly better ERA:
70 - 45
since Monday May 11 thru last night.
You decide for yourself how much meaning/validity this ratio may hold in coming matchups. Keep in mind that in almost all matchups with a significant difference the better ERA is usually laying heavier juice as the fav
