Hello some news for the problem!
I received an answer from Nikon Europe today:
Subject: Degraded speed with 800mm f / 5.6E
Hello Mr. Chappuis,
Thank you for your comeback.
Your procedure seems correct, currently we are still awaiting information.
This problem could be related to lenses with electromagnetic aperture control.
I will get back to you as soon as possible.
It seems to me that the problem continues in the investigation, let's wait patiently for the next feedback ...

Have a nice day!

Alain - thanks for keeping us posted. Strange that they said "This problem could be related to lenses with electromagnetic aperture control." I mean all Nikon latest supertele have electromagnetic aperture control if going by the "E" designation on the lenses.
The new firmware update may correct this. They don't mention this lens but do suggest it is correcting this problem. Released today
NO not this time. I will be notified as soon as Nikon Japan fixes and finds the problem. I will keep you posted.

According to conversations I have had with Nikon, yes all are concerned. What escapes me is that the other professionals responsible for testing the new hardware did not find the problem. For me, it immediately went off listening to the sound of the triggers according to the different diaphragms ...
I pushed the analysis with the bursts and with the help of NX Studio which gives the times in hundredths of a second for each shot. To differentiate the times between each photo and for each diaphargme was immediately obvious. Something I reported to Nikon for the veracity of the tests that was accepted.
According to my tests even at f: 5.6 the number of 14 fps is not respected, we are below.
Hello,
No fresh news and I'm still waiting for an answer from Nikon. I don't think I would have a view that all of Nikon's effort is in the Z program.
That said, I did some pretty extensive testing with the D6 + 800mm f/5.6E and discovered one thing:
I managed to pass the 14 IPS while being VR OFF, and f:5.6 which shows that the D6 does not provide enough voltage.
So for me it's a design error with this box. I have not done the tests with the D5. If someone here can do them it would be interesting to have a return to determine if the design error dates back to the D5.
I ran the test with z9 and 800fl. No change in speed 20fps at f5.6/f11/f16 with or without vr. I also tried it with 2xtc and no change in speed with or without vr at f8/f16. All in afs-c vr normal.
I do not own a D5/D6

Glad to read this answer, but which may well confirm my writings here above.
It would be nice to do the test with a fairly large diaphragm like f:8 or f:11 and see the shooting performance.
With VR, of course...
