Nope.
I bet he picks up a gun and mounts it and knows by feel whether he likes it or not.
Of course he is taking a non numerical measurement of those values and comparing it to his usual gun.
Just like Michael McIntosh did every time I shot with him. From a competition O/U, to a cast-on Dickson, to a custom Fox to what ever anyone handed him. Within a few shots he was breaking birds with each gun.
I wonder how the MOI measurer shoots with a variety of different guns.
Also, I wonder about the OP and how three different barrel configuration could possibly balance at the same point? at three different weights? Highly unlikely...
BTW: I was never condescending...
