Just to reinforce what Pete said, I had a chance to talk with Carlos Torano last Spring and he told me that the exact same cigar he made with three different bands was evaluated by CA with two scoring high eighties and one over ninety. I'm not sure if they were different shades or even a different size, but what he said was "the same cigar". In the context of that conversation he made it clear that the same blend went to maket with different bands from different companies.
To be perfectly fair, ALL cigar rating are nothing more than a subjective perception of the reviewer.
Naturally, there are a million little things in everyday life that can alter someone's perception...like what you've eaten, what you're drinking, the environment you're in, the mood you're in, whether you got a piece of ass last night, if your allergies are acting up, if your boss wants the stack of TPS reports on his desk by 8:00am tomorrow, if your grandmother just died, if the chili you had for lunch is running through your colon like a freight train, etc. etc. etc.
And yeah, it's possible that advertising dollars can cloud the judgment of a publisher (they are running a business after all) but I like to think that most magazines try to separate the advertising and editorial departments as much as possible.*
Just remember that cigar reviews aren't a science. You just gotta take them as a rough guide and understand where they come from.
* sidenote: I used to be an Art Director of a magazine, and our publisher was, without a doubt, heavily influenced by advertising dollars. So yeah, it happens. Not saying that's the case at CA, just saying that in the industry, it DOES happen.
