I was tempted, but it seemed overkill for just two ways.
Unless we do want to replicate all the other scale computation
algorithms found in the others projects, a simple if is enough.

Yes, there are only two. If anyone will come in and ask for 10 different
ways, we'll set up the strategy pattern. It did not pull its weight in
this case and in my opinion.

Yes, there is one... can't remember it, have a look at those closed today.
