Hi Victor,

I believe you applied the Referee Method incorrectly. I think you still
had
three corners against the granite block. (your R1-R2 of the Referee
Method
was close to your .042 measurement, and I would expect it to be half
that
measurement.)

Only 2 diagonal corners should be against the granite block (R2). The
other 2
diagonal corners should be raised to an equal height to each other (R1).
L in
your calculation should be the diagonal (14.75) not the length.

Hope this helps.

Brian
