I don't follow that line of thought at all -- why would any 
_deterioration_ cause a failure away from the glue line?  And what 
mechanism is supposedly at work doing this?

I think your proposed test (iiuc) will simply again demonstrate the 
point of maximum stress is in the middle of the panel and the variation 
in wood properties will make for a moderate difference in actual 
breaking point from one side to the other a la Heisenberg...
