You are very perceptive. I am fun at parties - and without any of the unpleasnt Australian boorish crowing sporting sledging that you seem to exemplify, and which has caused me not to follow cricket for 40 years.

Exactly, Mrs Bowers, and the place name should even include country and region/state/province.

Dear Dumbe, I usually enjoy your posts and agree with them, but I find your crowing about beating the Poms to be quite offensive. Mate, you are better than that.

Of course, "Middle East" would be more properly applied to South Asia. German uses "Nahe Ost" (Near East) more correctly to describe the Levant, but still with the Eurocentric problem.

Glen, very good stuff, thank you.
It might be better to use an exponential as approximating function $y = a0 + a1 * exp(a2*(t-t0))$ (one of those coefficients might be redundant). The underlying physical process might well be exponential. Of course, locally a parabola is a good approximation.
