I've started several times to critique this "miss", but have stopped short as I thought it would sound too critical! If it does, I apologize, but after all, we're here to learn!
In the videos, the crosshairs were dead on the coyote multiple times, but no shot was fired. This is indicative of several issues. .
Trigger adjustment is a fine line between safety and let-off. All too often, first stage travel is excessive, making a crisp let-off impossible. This fact makes off-hand shooting literally a hit or miss scenario. It also points to the need of a very good trigger group, even if that requires replacing it with say a Timney Calvin Elite. There is a reason they cost upwards of $300!
Too much magnification and/or incorrect parallax adjustment, especially at night, causes one's eyes to sciatically move across the exit pupil which changes the apparent POI. Adding insult, most night vision scopes do not have parallax adjustments—only a focus knob which is a whole different thing! This is true of the X-Sight II, and other similarly-priced night vision scopes (≤$1,000).
One way to improve offhand shooting, is to practice with a moving target. Some gun clubs have such setups, and a few hours of range time shooting at a moving target does wonders for one's trigger control. I still hit the range a couple of times a year just for this reason. I also hunt about 250 days per year, which does wonders for one's offhand skills.
And lastly... Any stimulant you use is going to cost you in more ways than one. This includes sugar, nitrosamines (due to flame broiled meat), citric acid (OJ), coffee, nicotine, and alcohol, even in moderate usage. Back in the early 70s, the FBI did a series of tests to derive the effects of these stimulants on shooting ability. The outcome was, and still is, obvious. Yet, almost all night hunters, gobble coffee, et. al., and hit the field on a full stomach. If you want calmer nerves, drink cranberry juice!
