Well, where can I get a copy of this spreadsheet?... either you've got
the wrong dimensions, or the spreadsheet is flawed.

The Sonex stalls clean at 46mph, and those are real verified numbers (no
I cant point you to a cafe study or anything but all builders on the
list who have actually flown one have verified their numbers..)

Is the airfoil type taken into account??

The Sonex numbers are believable, but absolutely DO NOT trust performance
figures provided by builders. Pitot/Static systems are notoriously
inaccurate at low airspeeds and owner/builders are notoriously optimistic in
their performance reports. In addition, without very expensive and
sensitive test equipment, you're not going to get accurate figures. There
isn't a CAFE report on the Sonex, so unless Sonex Ltd. has invested the time
and money to conduct private tests, my guess is that accurate testing simply
hasn't been done.
