I will try to dig up the tests or to recreate them.

You are probably correct that this is not a very large problem in practice. As 
I recall, I had to make the number of iterations quite large to see a 
substantial difference in time.

On the other hand, I did this test because I have a program that needs to 
perform a large number of three-way decisions like this.
