Sorry. Original phrasing around how we were now going to measure was pretty bad, I agree. I just edited it. I had been bothered by the very text you quoted, and we had an internal thread where we all discussed that and agreed that the phrases were wrong... but we were slow about that, and you commented while we were discussing! The new text more closely reflects the actual structure of how we've been thinking about it all.

It's a bit tricky to publish a long post with many co-editors without letting something inaccurate through (at least in a sleep-deprived marathon like we very rationally used before publishing this one...; there were a bunch of us working collaboratively on the text...); but we should probably in fact have edited a bit more before posting; anyhow, my apologies for editing this text on you after you commented.
