Very interesting article.
However, I oppose using the counts as a metric.
I happen to be writing a chess now (in java). It has tables implemented as 64 way switch statements. These obviously give a count of 64, but can you really say they are too complex? For example one takes one of 64 chess squares as an argument and returns a board with 2 to 8 squares where a knight can jump to. I know there are no bugs in the method because I printed out all 64 possible cases and checked them by hand.
So while the concept is very interesting I think there are exceptions where you don't want to just count all all the decidsion points.
