Let me know what you have in mind, I wouldnt even mind shooting a video to go with one. Once I got it zero'd in, its a good scope. It just sucked to try to go through the manual at the range.
Im still not sure if I should start with the infinity parallax setting, and leave it at that, or start at infinity and adjust to my shooting distance.

Here is the language that I put in our newer manuals regarding the parallax adjust. It doesn't matter where you start, but you need to adjust it to your shooting distance. Most people just adjust it until the target seems pretty much in focus, more or less, and leave it be. To maximize precision, here is the process that we recommend:
ADJUSTING PARALLAX
The Parallax Adjust knob is located on the left side of the scope, marked with ranges from 7.5 yards to infinity. Although it is often referred to as a “side focus” knob, parallax and focus are not the same thing. Parallax error occurs when the target’s image and the reticle are not aligned on the same focal plane inside the scope. Think of a mechanical car speedometer that seems to indicate a slightly different speed when you look at it from the passenger seat. Because the needle is positioned between you and the dial numbers, moving your head around changes where it seems to point. This creates an inconsistent picture depending on your point of view. Adjusting the Parallax Adjust knob eliminates parallax error at different ranges by bringing the reticle into the same focal plane as the target, like a digital speedometer displayed on a flat screen. Parallax error is most noticeable at high magnifications. Adjustment is much easier with your rifle secured by sandbags or a bipod.
1. Turn the Parallax Adjust knob until the target appears to be in focus. This will get you close to the correct adjustment.
2. Looking through the scope at the target, move your head just slightly from side to side. If you lose the sight picture you are moving too much. Go slowly, and see if the reticle appears to move relative to your target. A target that appears to be floating around the reticle as you move your head indicates parallax error.
3. If the target appears to move in the opposite direction of your head, turn the Side Focus Knob clockwise. If the target appears to move in the same direction as your head, turn the Side Focus Knob counter clockwise. These adjustments are very small. Move the Side Focus Knob just a little bit at a time and re-check.
4. Once the reticle and target hold their positions as you move your head from side to side, parallax error is eliminated for targets at this range. Normally this adjustment will also keep the target nicely in focus. However, to gain the most consistent hits on target, it is more important to eliminate parallax error than to have the target perfectly in focus.
EDIT: I took the above language from another scope's manual, so I'm not sure if the PA416X parallax knob's markings start at 7.5 yards or not, off the top of my head. But the procedure will work regardless.
