I decided to make a new thread out of this subject. As stated in a different thread, your Card Score points drop off a year after earning them. So, points earned earned in August 2013, will drop off your card ~Sept 2014. These are the points that determine the color of your card. I got an answer back from the slot manager today. Your slot points stay on your card for 3 years even if you don't have any activity. After that, they can purge them according to Gaming Control. He says they usually don't, but are allowed to do so. These slot points are the ones you use for food/beverage etc. Hope that clears up some of this.
