Perhaps you could explain to me how that works.

Focus and parallax are not the same thing.

The reticle and image can both be in focus, and you can still experience several MOA worth of parallax. This applies to both fixed power and variable power optics, and the higher the magnification the greater the effects of parallax can be.

There are a million articles that explain what parallax is, and how it affects POA/POI intersection.

I’m sure that if you were to leave your scope “focused so that everything is good between 70 and 200 yards”… that you will be experiencing some parallax issues at either 200 yards or 70 yards…. or to a lesser extent, both.

I don't doubt the sincerity of your statements but I still don't see the underlying reasons for those statements as applicable to a fixed 10 power second focal plane scope. So far, with the scope focused at 70 yards, Ive not noticed any parallax issues from 40 yards to 200 yards. That said, I'm pretty good at keeping my eye centered in the ocular so it may be that I just don't notice the parallax. The next time I'm out to the range with that scope, I'll make best efforts to look for it..

You are correct, if you have perfect form and position, parallax will not be a problem for you. I know many people who never knew the word, or had an adjustable one, and they shot awesome too. It does help many though.

From a static rest, parallax issues are mitigated… from field shooting positions, parallax issues are much more evident.
