Either way no sense arguing.. I dont even see the need for bench run ins anyhow.. throw it on the plane add Penzoil 50:1 tune it properly from day 1 and fly it. All this other stuff is a waste of time.
A test stand sure makes it easier to tune exhaust system / prop combos compared to doing the cutting and checking on the airframe. If you are running a pitts muffler or something generic like that it is not particularly useful, but can be very useful with tuned pipes or canisters.
