Agreed, and one caution: a single measurement is not a measurement.

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. The useful move here is to separate what is established from what is widely repeated. Those two sets overlap less than the confident tone of most write-ups suggests, and the second set is where nearly all the disagreement on this board comes from.

Adding the numbers, since they settle part of this. One habit that pays for itself: post the method alongside the number. A figure without its method cannot be checked, and an unchecked figure is how this community accumulates folklore.

One thing that is still open after rachel_ABQ’s answer:

Was that from a primary source or from a summary of one?

This is where I part company with the consensus forming above. Pushing back on the anecdote-stacking. Twenty people reporting the same thing is twenty samples from the same self-selected pool, not twenty independent confirmations.
