The resulting maximum deflection was 0.06" which is about

in my case of a 46" span, again well within my tolerances.


Huh? If .06 is 1/16, 1/32 should be .03. - .12 would be 1/8
(actually .125=1/8).


Deflection is .06" over 46" while eye can recognize 1/32" per RUNNING
FOOT, which would translate into about 0.12 (or 1/8") over the 46" length.


Ah, so! My goof!
