My understanding of the situation, and you have gotten tons of replies on this subject explaining this in detail, is that it doesn't make a difference.
You are trying to carry calculations out to the millionth decimal place, and no matter how far you keep extending beyond the decimal place, it will still only round up the whole number by a value of "1". It doesn't make any significant difference.
It wasn't a desert. The desert if FULL of insects, believe it or not. You can be in a DRY, BARREN DESERT and there will be FLIES. JUST ASK A CAMEL. Why do you think they have tails?

According to the canadian site on this, the fly production varies according to the weather so much that there are times when the fly data are not valid. If its true in one extreme environment why assume that its not true in another extreme environment.
Isn't it possible there are times in the desert when fly's are not so bountiful as to create an accurate time frame ? To the canadian expert the obvious answer is yes. TO the american expert the obvisous answer is no. To me the rational answer is given by the canadian expert.
