I did four RT (PHL, IND, LAX and PHX) with a regular size tube of toothpaste (not intentionally) in my shaving bag. It was on the last trip coming home that the screener caught my error and had the then nearly empty tube confiscated. I don't believe that means PHX is better than PHL, IND and LAX as the tube was nearly empty, just that the screener took the time to identify the items displayed on the screen instead of a cursory look.
