It might be so on that machine, but the amount of adjustment needs to be sufficient to handle the full production spread. Designers usually err on the more adjustment side because not enough available will crash the production line (Never popular...)
I've seen enough far offset twiddlepots, just to save a fixed resistor, but getting it right, with a nominal set having them at mid-span is a sign of care and quality.
