I agree.
Regarding .25" (6mm) accuracy of all shots at all ranges, presumably anywhere on the target, is a big ask. I don't think it is achievable. For one thing, as an acoustic starts leaking (due to holes in the rear as it gets shot out) we know that accuracy, or measurement quality, degrades. By in large I aim for and like to see 10th of 1/4 MOA on average. But that's just me. It's about 3mm at 300Y and 8mm at 800Y. Roughly.
The storage and operating temperatures are a bit unrealistic but possibly doable. Not sure about the lower -40 degF but the 122 degF upper storage and 113 degF upper operating temperatures should not be a problem with industrial grade equipment - I have industrial equipment here rated to 160 degF (junction temp). I don't think anyone here in Australia would ever get to shoot at 5 degF but during the summer just gone I had shooters using the system on a regular basis at 104 degF. I thought they were nuts... but the gear held up throughout. Apparently the shooters also! In general semiconductors hate heat. I think life expectancy will diminish when subjected to this sort of thing.
Overall I think in respect to acoustic ET's it's not a bad start. Not that what I think matters much so this is simply an observation. But who put it together (can I ask)? Is it simply a case of outlining "desirable and mandatory" features and standards now and later ask those who might now about the physics and limitations of ET's (especially acoustic ones) what are realistic expectations and deliverables? Who is actually defining the standards to which ET's need to meet in order to be certified?
This is mainly my curiosity. It doesn't really affect me. We don't have any such standards here in Australia. None that anyone takes any notice of anyway...
