If you are not seeing a change in tune by adding or removing the Magnetospeed, it would imply that making minor adjustments to a conventional rotating tuner wouldn't affect that barrel either? Because in affect a tuner adjustment is adding weight to one position on the barrel and removing same from another.

I think it is all about the weight & location of the tuner in relation to barrel stiffness (size & weight). The bayo of the Magnetospeed is quite light & if located on the barrel muzzle tightly & in the correct place it has little effect on tune & poi when it is mounted on the heavy barrels used in F Open. I believe that heavy barrels require more tuner weight to tune than light (Palma) barrels. There are other factors (theories) to consider too!!!!
