Mathhammer has it's place the problem is those guys have no idea what there talking about. In your point Chris you are correct and how they are using it is useless.
That being said I am math nut and statistics is just my thing. I can't help it and I do it all the time because how much I use it in my daily life. I can calculate odds on the fly and be pretty close. The only thing I use math for is to gauge what the probable outcome and looking at the bell curve in absolute. All they are doing is looking at a specific point in time with no understanding what could happen in the outlying curve.
