It seemed like a good starting value at the time; good enough to show you what the effect looks like without taking too much render time.

Ah cool. Thanks for the explanation. I was wondering if there was some calculation behind it. I swear some one once told me computer calculations are quicker if the number is even.

For some specific calculations, yes. But not in this case.
