Poor success rate I'd probably say about a 20% chance of getting the job done, we really don't get that many dogs that just sit and bark at us but it's always fun to try. I did it once by myself an then a couple of times with 2 people. Also depends on the definition of a sneak, I'm defining it as getting into a position to see the dog and shoot, could be a 300 yd shot. I'd bet if that coyote was only 150 yds or so and out of sight the chances would be about zero.
