how often does a weak intermediate player (little experience, knows very basic concepts, little/no concept of cube and match score implications, etc.) win against a world class player in a 9-11 point match?
The Elo formula is probably not terribly accurate for large differences in ability, but we can still see what it says. Suppose a world class player is rated 2000 and an average player is 1500. Your "weak intermediate" would be maybe 1400? That's a difference of 600 rating points, which equates to a 90.8% probability of winning an 11-point match.
In real life, I think the probability would be quite a bit higher. As soon as the WC player realizes his opponent has no deep knowledge of the game, he will start playing complicated games.
