As I said, Gulf News, Captains are notoriously bad at ATC. You are a Capt, right? Anyone at 7000' trying to do a CDA is not in the BUBIN or DESDI hold.
Perhaps if the controller wants a particular rate to achieve separation he or she should make it a requirement when giving the descent clearance.
I agree. Which is why a Capt doing the ATC is a bad idea.
