In order to keep pace with their Skyhawk we were throttled back to 20
inches of MP, and 2000 RPM.

What's your IAS at that power setting? I get about 150-155 MPH,
depending on temp, burning about 8 gph. I would get about 10 hours and
have a 30 minute reserve.

I have no idea. I was focused entirely on maintaining position with
Brian's 172 (we got some GREAT air-to-air pix), and never looked. GPS
ground speed was about 105 - 110 knots.

It was very, er, leisurely.

We were low, so I couldn't really lean back much. If we had gone up
to 6500 feet, I could easily have leaned to 8 gph at that power
setting, which, with 84 gallons, would allow a bladder-busting 10+
hour endurance.
