All true enough, but obviously you can't determine actual accuracy without shooting the gun, and with a new one you obviously can't shoot it before you buy it.
I think the point was more to check to see if the gun is put together well and check to see that everything is in alignment on a NEW gun. Maybe not a definitive test, but probably about the most you can do pre-purchase.
Seems like it would sure be better than nothing to me....
