I'm not sure why this is an argument. Here in the US, total medal counts have ALWAYS been how it's been listed on every TV and in every newspaper I can remember since I was old enough to care to look (1980? 1976?) - it's not a better or worse way of presenting the information, it's just how it always IS (has been) around here.
The trouble there is a fight with Fedor isn't really a big coup for anyone. Hendo's not such a big name that he'd pop the ratings overmuch, but more than that, the people who do know Hendo know him as a middleweight.
