an issue with no negative numbers in your W & B calculations. I guess
Alexander can't figure out subtraction.....
If that is the case.. use your nose wheel or the end of the float deck as
your datum so everything is postive behind it. Be sure to get an accurate
measurement to the center of the door post or leading edge for when you
switch to conventional gear and to convert the Murphy 7.7 to 19.7 (or what
ever the current spelled out) WING range to reflect your datum.. IE: your
empty C of G range is now gonna be MAM's numbers PLUS the distance from the
leading edge to the nose wheel or float deck end.

OK, I'll just take Wayne's empirical data report here as [almost]

forward of leading edge) and -- quite uncharacteristically -- say no
more.
And definitely, worry no more. ;-)

a hike
to and around 3979m (13,054 ft.) -- and lived to tell about it.

The Spring LEAF gear... without any extreme regard for measuring
accuracy...
with a leg on the work table, the axle centerline appears to be
7/8" AHEAD
of the door post center line!
