Here are some statistics on how Americans order their steaks. The trouble with this kind of thing is that the way some of us order our steaks is not the way we prefer our steaks. In most restaurants, I find I have to order a little rarer than I want to get what I want. And of course, you can always send back a steak that's undercooked and ask that they give it a little more time on the grill but you can't send back an overcooked piece of meat and ask that they subtract some of the cooking.
Also, since my gastric bypass surgery eleven years ago, I have to keep in mind that in most restaurants, I'm ordering what I'll eat half of now and eat the rest of, later or the next day. If I get my steak cooked to the rarest level that I find acceptable, then the leftovers are still fine when I reheat and they cook a bit more.
