Yeah, my statement comes from my experiences coordinating Organized Play tables at conventions. I've seen plenty of groups of one GM + 2/3 players, where the end result is pretty skewed. You get good at identifying possible problem areas. Or, I guess, you field a lot of complaints from dissatisfied con-goers, also an option.
Honestly, it strikes me as trying to do a good job presenting the right experience at convention games is a pain in the behind. I haven't done it in decades, and back when I did there was a stronger common set of expectations than there is now.
