A sigh of relief as I hand-calc-ed the tank I filled tonight. It was #9, and through all the hard work and mounds of help I've received from GH and particularly my fellow HCHers, I managed to set my personal bests in mileage and FE, and topped 50 MPG for the first time ever. It feels great hitting landmarks, but even better is knowing this is just the beginning of what's to come. Thanks for the help everyone.
