Fortunately, the author of the article is not one of the semi-finalists cited. The entire article is pretty poorly written.
Not familiar with McClure ... is he still around?
I never understood why so many people have trouble working with percentages. Many, perhaps most, of the populace don't understand that if you take 100 of something, and reduce it by 50% to 50, that you have to increase the result by 100% to get back to where you started. It's a simple concept, but apparently above the heads of many. They would say since you reduced by 50%, you'd only have to increase by 50% to get the original number.
