From the other side of the consultation, briefly. 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.

A narrower follow-up, since the general answer is now clear:

How long did you give it before you decided it was working?

I am going to disagree with the direction of travel here. The thread has converged on the tidiest answer rather than the best-supported one, and those are not the same thing.

No disagreement, though the timescale matters more than the mechanism here. Most of what looks like a difference in kind turns out to be a difference in how long somebody waited.

Ask again with the specifics and you will get a better answer than this one.

Moderator note: leaving this open. It is being argued well and the disagreement is the useful part. No action needed from anybody.
