Say what you would expect to see if you were wrong, before you look.

This is exactly what I could not find anywhere else. Sending this to two other people who asked me the same thing last week.

Reporting back.

Following up because I said I would. I changed one thing, left everything else alone, and waited the full interval before looking. It resolved, and I cannot prove which half of that did it.

Mine went the same way, slower.

There is a second half to this that has not been said yet. Take it one variable at a time. Almost every unanswerable question in these threads is unanswerable because three things changed in the same fortnight, and no amount of subsequent argument can untangle them after the fact.

Adding the numbers, since they settle part of this. One practical note: write down what you did and when, before you need it. Reconstructing a timeline from memory three months later is how people end up unable to answer the one question that would have resolved it.

I would rather be corrected than agreed with, if it comes to it.
