I'm a little skeptical about the doubling, but have always gotten 10-20% better than EPA from my vehicles.

The delta on a hybrid will always be lower as it does some of the hypermiling for you, and it was probably bought by a more genteel driver in the first place.
100% over EPA is definitely possible. Heck I've done a fair few trips that were 100% over NEDC.
