Anyone equipped their 2nd Gen Prius with them to see?

Attached is my MPG spreadsheet showing the relative performance of my OE GY Integrity tires for the first 44,500 miles and then my Michelin MXV4+ "Energy Saving" (read LRR) tires for about an equal number of miles (the Michelins are still going at 90,700 miles).

Note: Its not just the sidewall that determines rolling resistance. Most LRR tires use Organo-Silicates in the rubber compound to lower heat generation due to flexing.
