Not for a precise ratio, no. But logic does allow the broad
generalisation that if test one takes between nine and ten seconds and
test two takes between zero and one seconds, then test two completes in a
shorter time. If both tests are aimed at - and achieve - the same result,
then the method involved in test two is quicker. :-)

That's right.

Once it gets to that sort of result, the precise ratio isn't import. I've
already made up my mind about which method I prefer! :-)
