The trick these days is not so much in having the VRPs in the database (and up to date...which some systems still aren't so good at) but how quickly you can add them to your route without losing your plan, when you're in a busy phase of flight.
I find that VRPs, especially unexpected ones, are nearly always used at the end of the flight, to get you into the circuit without too much fuss. May I kindly suggest that if you start updating the route in your GPS with the new VRPs, at this stage of the flight, you don't have your priorities straight?
