CFD.
I think this is one of the creeping problems and a visit to a centre might help. When there is dead time on the R/T we are
1. planning 2 moving new traffic into the plan 3. telephone calls for coordination/planning hold/speaking to the military 4. working a plan with my colleague. 5,. etccccccccc.
While puting in the adjacent point in your FMS is a superb idea, may I suggest you then fly the published speed and cut down on the R/t. This may mean you are 3 minutes slower into wherever but the controller has extra thinking time and you may avoid the hold(4 mins+).
We try to provide the best service and let me tell you the guys I work alongside are superb. We do not tell you when to select flaps/ gear/ that little light to tell people to sit down. Please do the same for us.
