tdbru, I don't know anybody who has examined this issue with electro-optics. Given that the adjustments are electronic, they are the same every time. I have seen where the windage is slightly different than the elevation before and that is the only inconsistent aspect I have seen.
The increments of adjustment aren't always what you would expect, either. I have never seen them in mils or MOA. They are just some present amount. I don't know if it is this way on the SY or not, but on the Trijicon, the amount of change varies with the level of magnification, which is really cool, but sometimes frustrating, where native magnification has the largest adjustments, 2x is half the distance, 4x half of that, etc. The SY has a one shot zeroing system where you fire at your target, note the POI, and keeping the same POA (and where is a dot in the zeroing setup that holds the original zero point), you move the crosshairs to the point of impact and save the setting and you have basically gotten zeroed.
Quite simply put, most people do not make field adjustments on their thermals. A survey done years ago on Texas Hunting forum found that something like 90-95% of hunters typically only shoot within 100 yards. 97% (or 98%?) within 200 yards. While some did have longer maximum distance shots, such shots were the very rare exception for the vast majority of hunters.
This is particularly true for thermal hunters. Why is that? Lots of reasons. I have heard a lot of people say it isn't safe to shoot over 100 yards at night. I have never understood this sentiment on why 100 yards was a magic stopping point, but there are folks that definitely feel that they need to limit their shooting. Due to resolution, the farther your target, the fewer pixels that will make up your target and hence the greater the difficulty in making proper identifications and aiming precisely. Conditions at night (when most folks use thermal) are less optimal more often than you would expect with day hunting. At night, humidity goes up (degrading thermal conditions) and there is a greater chance for fog as well. While thermal does see through fog better than day optics, fog is still a limiting hindrance. Also, in most cases, getting to the menu setting on electro-optics to make zero adjustments is a pain in the butt in terms of the number of steps and time that it takes.
When folks compensate for distance and wind on the rare occasions that they do, it is usually Kentuckian.
I believe ATN has a LRF scope that will use a ranged distance and move the crosshair accordingly based on dope input for your ballistic data. I don't know much more about it than that or how good it is.
