In a healthy relationship either person should be able to give feedback spontaneously. If the client is only expected to give feedback when formally asked, that seems paternalistic and controlling and just downright weird. I would be bothered by it.

Seems therapists get confused and think they are overseeing some controlled process, and thus need to collect data like a scientist. Seems really bizarre to try to quantify "performance" in a human relationship. It suggests that they are acting and would adopt a new persona if the client didn't like the current one.
