Years ago, my ADT was trashed by the time I finally learned that sticking in my CET card into a kiosk to monitor my RC's triggered gaming days.
It caused me to avoid CET action for a couple of years, I guess that was enough time to "reset" when I gave it action again.
If parking triggers a gaming day, then you had better guard your Platinum and higher tier card and not leave it in a machine. Because that will allow someone to take it and get free parking to your detriment which will give free parking to another, while trashing your ADT. If parking does not trigger a gaming day, then such a scenario would be of little consequence.
