Well, this is unscientific, but here goes:

Number of DHL/World / non RJ guys that have attempted to overspeed the bus on me due to their
pathological need to be in vertical speed = 0.

RJ guys = common occurence.

Even worse lately with the higher CI's we are using

Max climb rate +/- 1000' from assigned altitude is 1,500 FPM for that reason. Most ignore the AIM "recommendation" however.

Or the Old crusties that get a Speed reduction and descent downwind to base and pull for Open Descent. Unreal. They wonder why they are always high.

Perfect situation to use V/S.

Are you the guy descending at 1000 fpm with the engine power up at 55%, using full spoilers, and wondered why the ECAM is flashing Amber 'Flight Spoilers'??

And by the way, it doesn't matter what mode of the autopilot is being used. The laws of physics and aerodynamics don't change depending on what a/p mode you select.

How fast you lose altitude in your scenario will always be a function of your airspeed, configuration, and engine power.

In your scenario of needing to go down and slow down, adding engine power does not help.

When using 'open descent', the aircraft honors the speed first and then the altitude (without the addition of any engine power). If you want to get down faster, you can select a higher speed until after the altitude loss.

If you are at at 5,000 ft and Doing 250 and told to "slow to 200 and descent and maintain 2000, turn HDG blah blah. In Open descent it won't really start coming down until the speed is back. Why not dial in -1,000ft and spin the airspeed to 200? It will immediately go to idle and almost immediately start the descent as opposed to the lethargic open descent and roll speed back method.
