Forgive my cynicism, but I see searches for alternate metrics as probable fishing expeditions for silver linings on falling behind.
Looking at the results, and the above example of IE doing well in the past, everything seems to neatly inversely correlate with my experiences when checking caniuse.com for recent standards. (At the few sites where firefox does worse than chrome, I would wonder if the site is written for firefox then made adequate on the others == less -webkit-css and more attentions to the "best" -moz-css animations, etc.)
Since IE was the biggest failure on caniuse but is rapidly being eclipsed by safari, naturally they must pass the best power usage baton as well if they can be coaxed into otherwise equivalent environments.
A standard to handle graceful prioritization and intentional degradation for power saving could perhaps put this trick to sleep.
