Worth separating two things that the opening post runs together.

18-month record is worth one more sentence than it usually gets, and the sentence is the one about how the number was arrived at.

The opening post is right about the mechanism and I think understates the practical bit.

The best progress reports here read as records rather than as arguments, and that difference is visible within a sentence.

Where I would push back on the 18-month record consensus is the confidence, not the direction. The direction looks right. The confidence is borrowed.

Worth separating two things that post #24 runs together.

The honest answer on 18-month record is that it depends, and the useful part is the list of what it depends on. Four items, in rough order of how much they matter.

Most people get the first two right and then argue about the fourth.

That is a fair summary of where the discussion has got to.

I would rather this thread reach "we do not know" about 18-month record than reach a confident answer that nobody can support when asked.

That is a cleaner way of putting what I was circling around.

Photographs at fixed intervals under fixed conditions are a better record of composition change than the scale, and much harder to standardise.

Noted, and I have changed what I was going to do on the strength of it.
