Nearly-static content is where you want even fewer keyframes than usual. In a situation like this you need them when the connection is interrupted and you reset things, and not much of anywhere else.
You wouldn’t use 1fps in conjunction with GOP 60. The original article wanted exactly one key frame every 60 frames and the server drops all frames other than keyframes. I was pointing out that this is a roundabout way of achieving 1 fps.
