2X Points Package & Q3 2013 Stackable?

Recently, I took the 2X Points package for an extra $10 USD. Checked my Hhonors account.

Base was 1609 and then received another 1609 for the 2x package. Then I received 3218 for the Q3 (weekend double points stay). And 402 for the 25% gold member bonus.

Question: should I have received 6,436 as a Q3 bonus and 805 for the gold bonus?

As a side note, I saw I received a 50% bonus on points for 804 points. What is that bonus for anyway?

Thanks!
