Center seam of guitar

Is there any research on the long term effect of enhanced vibrations on the rear center seam of the guitar?

I've been using it for 2 years and it hasn't changed at all. 

The grain direction of the seam strip is perpendicular to the seam, which should prevent any separation unless the guitar is too dry, then the wood will start to separate at the seam.

The TWA hasn't caused any issues with mine.



The strings alone provide a ton of vibration. The glues and clamping process we use making guitars is designed to withstand lifetimes of vibration.
