From what I've seen from the AP wires and such, nope; Each ratings point represents 1,067,000 households.
So, that would say SD's rating is doing better than Raw, period.

I think the guy meant that since RAW is available to more people, that it should be expected to get a higher rating based on that alone (which is true). Smackdown always has a hill to climb because of the difference in ratios of how many people ARE watching to how many people COULD be watching.
Actually, once upon a time, numbers from Broadcast Television meant more than Cable television because more people have access to Broadcast than Cable. So a 4.1 for a CBS/NBC/Whatever show means more people were watching than a 4.1 for ESPN/Comedy Central. But they redid the ratings in the past couple years, so I don't know if they're balanced now.
So today, RAW's 3.7 is actually bigger than a 3.7 from over 2 years ago.
