Hi Ed,

 It was not a test -- and not max range.  It was the first leg of a trip up to Oregon Aero for upholstering.  I stopped at Orange County and Santa Rosa to give long-promised rides to friends.  The record is still available on Flightaware > N550KC.  The trip from Grand Prairie to Orange County is summarized below.  Fuel use is based on gas pump readings at each airport.  You're right, I excluded the speed brake pockets and got 74.4 gal total usable (as measured on ground; I haven't run the tanks dry in flight like you have; but then I'm not planning on crossing the Atlantic like you did!).  I did not add any other tanks.  With 19.0 gallons left, I had plenty of reserve for an IFR alternate +45 minutes.  There was a 20kt tailwind for the first half of the trip and mixed winds for the second half.

Summary:

5:22 from liftoff to touchdown.

55.4g from top-off at GPM to top-off at SNA.

Cruise fuel flow:  9.8 gph at 18.8" / 2300 / 12000 ft / 167 kias / 206 ktas; I don't have ram air, that's wide-open throttle through an ordinary K&N filter.

Great-circle distance was 1047nm.  Each new Center sector controller gave me some re-routing so there was probably an extra 100+ nm flown.

Note:  All the dudes out there (not to name Clark Baker, for example) who've really done it right and got all the low drag mods, have pity on me; this airplane doesn't even have smooth paint on it yet.  However, recent micro work around the lower surface inspection panels, to make them flush, appears to have given me a couple of knots.

I saw two LNC2s taking off from Orange County at around 11:30 am -- nice to see.  I'm the ONLY Lancair at Grand Prairie and have to keep explaining it's not a turboprop, it's not a Columbia, I don't fly the pattern at 70 knots, ...
