Regen and Mileage

Saw my first regen cycle on the temp guage yesterday. Driving along on the Interstate getting the tyical 17 on the overhead (usually 15.5-16 by hand when empty) and whamo the temp guage goes up 300 degrees over normal driving and the overhead starts dropping fast! It bottomed out at 13.3 and when the regen stopped it started back up. It got back to 14.7 Now, I drove half a tank (26 gallons) at 17 and then in 80 miles went down to 13.3 and it took the rest of the tank to get up to 14.7 I can imagine that if your truck is doing the regen repeatedly the mileage is suffering. I'm confident that when this gets solved either by cummins/DC or "solved" by aftermarket companies we will see greatly increased efficiency out of these trucks. Having the C&C I don't think I'm seeing the regens that the trucks are having. I'm also going to start running b20 this week as it looks to me that it will decrease the need for active regens and burn most of the particulates during passive. Anyone out there running bio consistantly in a 6.7 that could confirm/deny this thought?
