I’m not sure too many people use
lean of peak to do an engine break-in though. Also his direction of flight
tends to have headwinds so it would take more fuel than the flight you
referenced. He did not go at high altitude.
My Legacy has a TSIO-550, so I am really
not up to speed on what fuel usage would be at 10,000’, doing an engine
break-in rich of peak; but I suspect that that his actual range (tanks dry),
under the listed parameters is his actual impact point.

At high
altitude, a stock Legacy with IO-550 should burn approximately 10.5
gallons/hour using "lean-of-peak" technique. In
this example, actual flight time was over four hours with 21 gallons remaining
(66-gallon capacity). Please see: http://flightaware.com/live/flight/N767EM

Flight Aware shows 3 hours 50 min,
not 3 hours 15 min. That is a long way on 60 gallons..
If, as has been reported, the engine was
new, I would think that it was still being broken in. This would lead me to
thing that fuel flow would be on the high side; thus reducing range.
