    Is it more useful to have a Parallax adjustment that spans most of a revolution of the knob versus an adjustment knob that goes from 50m to infinity in 1/3 of a revolution?

    I realize that the range markings on the Parallax adjustment are just approximate, but it seems to me that if the range markings are spread out more it might be easier to get close quickly.
     
    It really depends on the sensitivity of the optic. The high end optics I own have a wide range of rotation and adjustment. The finer you can adjust the more accurate you can dial the parallax. Some might say it's better to have a fast adjustment?

    Personally I like having a wide range. But remember with many optics it's a matter of dialing parallax with the that knob or dial then using the diopter ring to fine tune.

    Do you adjust the parraax to the yardage you are at then focus or do you turn the parallax till it is in focus?

    The best method for me is looking through and dial till I'm in focus. Then without trying to upset the rifle stay on target and move your head up and down or left to right slightly to make sure the reticle is not floating around over the target, essentially making sure by visual inspection that your locked on. Now, there are some optics like the Schmidt and Bender 25x or the Steiner 25x where you just dial your distance and it's going to be locked on almost perfectly. The Kahles is not that bad either.

    My IOR, Premier, Nightforce were all over the map and not completely accurate. Actually the Premier doesn't even have marked distances. I.E. read below.

    You will notice some optics don't even bother to put the distance on the parallax knob, this is because of known inaccuracies and variances in the system or your eyesight and other variables.
