Chrome for Android Update Getting Better SunSpider Score on Nexus 7

I don't know if this is just a fluke but I noticed Chrome performance is better after I updated it on my Nexus 7. Because of this I ran the SunSpider benchmark on my Nexus 7 in Chrome and got a score of 1444ms. Not a huge increase but I did notice all benchmarks before the update are in the 1650ms range. The release notes for the Chrome update did say performance should be improved. Am I crazy? Maybe Google is finally making Chrome for Android perform like it should be.
