Gem Mania Complaint.

Final boss (Rock) destroys 49 yellow gems guaranteed (when mp is full) four times during each stipulation match. That's 4,900 points @ 100 points per yellow gem. Total score should be no less than19,600 points to easily clear second round. How in the world does the last match of the second round end with less than 18,000 points; blocking access to the 3rd round of stipulation matches?
