But I'm not commenting on shift speed. In fact I would assume shift speed would be the same given the same other parameters. I am just suggesting that the decision logic on when to issue the shift command was timed incorrectly under these circumstances. I feel this logic has been improved in the 991 PDK.
It appears the 991 PDK does a better job knowing when to shift.

I don't think the PDK software can do a better job of knowing when to shift than a really good driver - drivers can see things the computer can't. And even with my more recreational driving ability, I prefer having full control of when the shifts happen. That can be done in manual mode with the paddles/buttons of PDK, but then I'd rather have the physicality of MT.
Computers can fly planes, launch rockets into space, guide missiles with utmost precision and somehow you think shifting a gear is too hard for a computer to figure out??

I took to the Cayman to autocross yesterday. Based on the course design, I gave a lot of thought to when to shift from 1st to 2nd, and whether to try shifting back to 1st for some of the sharper corners. There's no way the computer, as currently configured, can account for all the things I did.
People have tried for decades to create meaningful artificial intelligence (AI), but with meager results so far, and no breakthroughs apparent on the horizon. There are plenty of situations where computers can't compete with human judgment, especially expert judgment.

Again, thanks all for a great discussion. My two cents. It is the use of better and what is actually better that may be failing. The PDK and it's programming is likely better than human in one sense, but it is not better at shifting when you would. Said another way it might be better at shifting when you should, but it is not going to be great at shifting when you would. Putting it in manual allows you to shift when your mind and judgement say go - and that is, of course, better in that it matches your expectations.

Interesting debate here...but I think there have been enough posts talking about the improved PDK of the 991 to suggest something is better in the 991. Whethere it's worth an upgrade is another story.
I chuckle when I hear using the PDK in manual mode. Isn't it an auto-manual mode since you can't screw up since the computer will not allow a missed shift.
For street driving either PDK system is probable more than most people need but why not have the best if you have the cash.
Im curious why you went with the PDCC since you have never tracked a car and I doubt there is much you will gain from it on public roads. An even plusher ride? Not sure that it will change the ride that significantly.
Good luck it's a fine set up.

2) Over rev commands are ignored (or cut off) in any mode (manual or auto) .
3) PDCC -- I wanted the complete system rather than an incomplete one .
It diesn't matter if the car is tracked or not . In fact even a track driver using a 911 to drive on the street to work isn't using those miles to the cars full potential and I doubt he cares.

The computer can not read the stop and go nature of moderate traffic . PDK also can not read an incline unless one modulates the throttle to kickdown the gear shift.
One can override the shifts with paddles but i found it easier to shift manually altogether. Plus the 2 to 1 downshift on the 997 was awful .
I did say this a long timev ago . PDK is great for heavy traffic or full WOT driving but it's the in between daily driving that it was lacking in the 997 . The 991 PDK on the other hand has really got this part remedied !!!!

The planes , rockets and missiles are not mass produced Porsches and to create a car with that type of sohistication woild cost a heck of a lot more than a 991.

There either is or isn't a difference in the PDK .
1) "But its PDK is no different than a 997.2 PDK"
2) "Trust me, no difference between a properly calibrated 997.2 PDK and the 991 "
3) " I am sure the 991 PDK is different than the 997.2 PDK "
Nuff said.

1) Manual Mode - Many PDK drivers opt to use it but in my case I like shifting gears but also having the option to sit in auto mode in heavy traffic . Also the shifts are extremely fast compared to a manual .
2) Over rev commands are ignored (or cut off) in any mode (manual or auto) .
3) PDCC -- I wanted the complete system rather than an incomplete one .
It diesn't matter if the car is tracked or not . In fact even a track driver using a 911 to drive on the street to work isn't using those miles to the cars full potential and I doubt he cares.

3) Complete system? Never heard it called that...I would use the term all the bells and whistles.
Buyers who track their cars choose options with the track in mind. And PDCC and PASM+ are probable the two that are pondered the most.
