Wow. That was super fast! A quick glance at this and it looks like it'll do the trick!
One suggestion comes to mind, though others with more experience than me may disagree or have more to add here, is that, on tall targets, having a true vertical line bisecting the centre of the target grid area is important to identify cant in the scope/reticle. If your POIs are not landing parallel or perfectly superimposed onto the true vertical line, then it may be indicative of cant, which requires attention. Without this line, it would be more difficult to identify cant. For example,

I've also seen tall targets with perpendicular tick marks along the vertical line at important MOA or MIL intervals, usually whole numbers. (Tick mark at 1 MOA, 2 MOA, etc.) Although, your target grid already has these, so this might be less important of a feature than having that bisecting vertical line.
Thoughts?
