I get rubber-legged standing on the third highest rung of a tall ladder (the highest rung you can safely put your feet on). I don't know how some people are able to stand on the very top and do their work without a care in the world. One misstep or something collides with the ladder from below and you're fucked.
Asking an average-taking machine to take the same average twice is going to look pretty similar yeah. It's kinda freaky because it's new and a black box, but the reason it looks similar is hilariously boring. This is the statistical average of TV installation guides.
