I have only one scope that is close. The others are so far off as to be worthless and unusable. So, I don't even look at the markings. I just do what has to be done. I adjust the parallax while doing the "head-bob" until the target appears stationary. You see Ted and all the other experts doing the same thing. Unless you wish to go to the same trouble as the FT guys in making large custom parallax wheels and marking them yourself, you have no other option. Most smart scope shoppers look for more important details like the quality of the glass and design of the reticle and the preciseness of the turrets. Not so much importance is placed on the accuracy of the parallax markings. Personally, if I wished to be a respected scope manufacturer, I wouldn't let a scope out the door unless the parallax adjustment and it's markings were as precise as the turrets. But that's obviously not the demand of the consumer, so sloppiness is common.
