I took me a while to figure out why there was no Quick Reply field. My first reaction? Sorry, not sorry; let's take it to The Lounge, where you-know-who doesn't go.
I will point out that zeroth order would be a Wild *ss Guess. First order is more appropriate for Rule of Thumb. What it comes down to is the significant digits. 4000 vs 3900 vs 3914 or 0.1 vs 0.01 vs 0.001, etc. So zeroth order has one significant digit that could be off by an order of magnitude.
