Travelweary: I stand corrected. From the first few posts before mine, it looked clear that non-elites were getting 5-for-5, Silvers were getting 5-for-10, and Golds/Plats were getting 10-for-20 or 15-for-30.
After reading all of the later posts, I'm in agreement that there's nothing straightforward about who gets what award. I guess I'm happy with my 5-for-10. I'd rather have that than 15-for-15. Maybe they are using a random number generator???
