True, with the qualification that this is a self-selected group. The people for whom it did not work post less, and that shapes everything we think we know.

From the other side of the consultation, briefly. Start from the measurement rather than the conclusion. Almost every disagreement here turns out to be two people measuring different things and comparing the numbers anyway.

Same experience, arrived at from the opposite direction. Posting only so the count is not one.

Adding the part of the answer the thread has not reached. It helps to ask what evidence would change your mind before you look at any. If nothing would, the discussion is not about evidence, and it is better to say so early than to spend nine posts discovering it.
