O yes, right... those econ guys... making the independent variable (price) go vertical, contrary to any purist-math guys...! Inverted functions. Or maybe I'm wrong, whatever (econ-wise). I remember that from there now. Way I would call it is whether the MV/charge variation is more linear vs non-linear. Within boundary conditions, MV vs powder charge should be linear in a perfect world.
At any rate, with powder grains as the horizontal independent variable, a flatter line, if not due to statistical-distribution issues, would mean no or very little MV change for a powder change in that region. Which, to me, sounds great but in theory should not occur since more powder means more pressure-gas generation-more energy to push the bullet and accelerate it. But you could take it to mean that for your particular measuring technology at your bench, whatever small powder variations that occur in your measures would not affect MV very much. Uncertainties and uncontrollable variables could and probably will mask/obscure that, however...
If somebody wants to use the 10-round method, fine by me. But I have no plans to do it.
