It's so nice to see people critique products they know nothing about with absolutely no useful context!

You do realize that I gave a much simplified view of the situation as this is a web forum discussing a related subject, not an actual design review of the instrument, right?

To any process I can set multiple "acceptable ranges" depending on what I want to accomplish. There can be a "reject" range, "ok, but warning" range, "perfect, no problem" range, or a "machine must be broken" range

Everything is context dependent; nothing is absolute.
