True, and it depends on a baseline nobody has stated. Without knowing where someone started, the same number can be an excellent result or a disappointing one.

Thank you — that is the clearest version of this I have read, and I have read a lot of them. Taking it to my next appointment.

From the other side of the consultation, briefly. The version of this that has an answer is narrower than the version being asked. Narrow it and it becomes tractable; leave it broad and the thread will produce nine confident and incompatible replies.

This is my experience too, for whatever a second data point is worth.

Adding the part of the answer the thread has not reached. It is worth asking what the claim would look like if it were false. If nothing would look different, it is not a claim about the world and no amount of discussion will settle it.
