Their argument is ultimately that with the AMP, they get ‘scientific’ starting points for their settings and that’s a perceived advantage. Thus they can ignore the advantage the QA has for automated feeding, which apparently matters more to some than others.
I personally appreciate that there’s competition in the market. I’m not happy with the price increase, but blame no one or thing for it except market forces.
Sub-note: I absolutely do understand and appreciate the testing and engineering behind quantifying the temperature zones with respect to each cartridge type and the programming it takes. It’s just that it doesn’t strike me as being critical for a regular use basis. Sure, if you shoot 10 calibers or more and tend to swap around often, there’s a benefit for your use.
