I think we can safely say boarding is the one thing we can rely on VS to consistently not get right! Its not that difficult surely? And you don't even need any signs for priority lanes, though it is always better when used!
Call 1: All Upper Class pax and Gold Card holders to board and those who require special assistance
Call 2: All Premium Economy pax
Call 3: Those in the back half of Economy to board
Call 4: Anyone left at the gate.
Then a suitably timed call in the Clubhouse for anyone there to head for immediate boarding.
When travelling in Upper I do have a habit of presenting myself to the front of the queue for boarding.
