Anecdotes not being data and all that, both you and I had the same experience of that number being too high for us to lose weight. I don't have time to look for actual research on what the right averages should be, but the mor important point is that the averages are relatively unimportant:

What matters is not what the average burn rate for your build is, but what you burn. And you yourself is the source for that calorie intake being too high for you.

The averages matters for generc advice and as a starting point, but they can never be as good as measuring and adjusting.

And I think that is part of the problem with this advice. Too many people seem to influence their intake by it but then get surprised and dejected when they don't get the result they expect, instead of using their result to tweak their intake accordingly.
