The geometry is such that the bending moment is maximized at the 
midpoint between the sup****t points -- that's fact.

Anything that causes it to break in another location is either a weak 
point in the material or a flaw in the joint.

That they don't (typically) break along the glue line is proof positive 
the glue bond is at least as strong as the mean strength of the wood.

The test has been done both scientifically and empirically enough that 
there simply isn't any doubt of the general principles in play here...

In an informal test environment the variability in the test itself will 
probably negate much chance of proving anything conclusive unfortunately.
