Following through from that thought about 2015, there was a
Head for Points article earlier that year with the following numbers from a similar document for a day:-
Premier: 55
Gold: 2,982
Silver: 2,416
Bronze: 2,081
This is broadly consistent with the numbers on the lounge brief from later that year, and broadly consistent with the numbers quoted by
fourstardust, other than the number of Silvers which appears to be out by something like a factor of 10.
