Don't I wish... so I guess maintaining 23 MPH in a solo effort probably isn't in my future, either.

I was just doing intervals today on Fiesta. I warmed up with a short lap at 315 - hands on the hoods relaxed, un-aero posture, 315 avg watts got me 23.7 mph (22.2 in the headwind, 25.4 in the tailwind). It was windy today, so I imagine that would be faster in calmer conditions. Also, I have significantly greater frontal area than you. You can do it.
