Jacki, it's probably related to the way people play. I'm ("vizal") ranked 105th for rosettes in the Standard puzzle, but I'm ranked 40th for common words in that puzzle. I play almost every puzzle, and I almost always keep playing the puzzle till I've got all the common words I can come up with, which means I often get pretty close to getting a rosette, but only occasionally succeed (50 times up to the end of September). There might be other players who play less often, but almost always get a rosette when they do play. They could find fewer common words over the year than me, because they play fewer puzzles. But they might have more rosettes, because they're better at it. (The swine!)
