Fly in/out DEN almost every week...

Check in online with electronic boarding pass
Never check bags
Park at Canopy Parking and take the shuttle to the terminal
Go straight to the Clear line
Usually no more than one person in front of me in Clear line, but often have to join a line with many INfrequent travelers in it due to the location of the Clear lane... longest wait is between the exit of the Clear lane and getting through the metal detector

PM if you want any specifics...
