Sportshift gear change question

For those who have experience with V8V sportshift ASM1, has anyone had any issues in up shifts? I always drive in manual shift mode. When I pull the right paddle near redline under full throttle, normally I expect hypershift to immediate shift and feel a little kick. Recently, I experienced couple of times in 1st-2nd where shift did not immediately engage. Then it hits the rev limiter and rev drops for about a second before it responds to my up shift commands.

I haven't really tried it too many times, I am guessing hypershift is hard on my clutch? Maybe my timing is off and hit the shift too late? 1st gear revs up awfully fast. Or is this a sign of clutch wear? Read too many posts here about folks with clutch problems... I'm at 12k miles. All other gear change scenarios still seem to work seamlessly. It's a tricky system to get use to and I'm still figuring out all the nuances by trial/error. It's great fun when it works just right.

I'm still trying to learn the paddles too. Sounds weird, but on my DB9 using the paddles I feel like I have to do it backwards to make it quick and smooth.

Pull on the paddle, then come of the throttle a touch then hit the throttle again.

If I pull the paddles without coming off the throttle it feels like a slow sluggish shift. If I lift my foot then pull the paddle (acting as if it's a manual) it's very clunky and not smooth.

Surprised me when I tried pulling the paddle before coming off throttle how much quicker and smoother it is. Almost like there is a built in time delay if you leave the foot planted and shift. :-)

But I sure don't know the "correct" way, just what seems to work on mine.

Different transmissions Conqueror. Sportshift in a Vantage is an automated manual with robotic clutch operation. You have a standard torque converter automatic in your car. Keep your foot in it when upshifting

The further up the rev range you are the more a slight lift helps the change
Assuming you are doing clutch learns as well!

I normally do the slight lift and can achieve a very smooth and pretty fast gear changes. But the manual and sportshift guide all say the quickest gear change happens during max throttle, hence I wanted to try it. When this work as advertised, it feels like driving a manual and let the clutch out very quickly, like someone kicked you in the back. Common sense tells me it's probably not good for the clutch, may be the manual should include a footnote?

I definitely could be an early sign of of the clutch being worn. Its also possible that doing a couple of clutch learns would eliminate the issue.

High rpm shifts does not necessarily wear the clutch faster as it engages/disengages quicker than sluggish low speed romping around. I bet taking off the line is many factors worse for clutch wear than high rpm shifts. Reverse, up hill, is basically shaving chunks out of your clutch by comparison.

Drive it like you stole it and don't worry about the clutch. Replace it when it needs replacing then drive some more.

Actually driving on the highway has more wear on the clutch than normal stop and taking off from a light driving..example, a clutch almost on its way out will not cause any concerns at low speeds and taking off from a stop, u will just have a higher than normal pedal as a sign...but get on the highway and try to accelerate in 4th, 5th, 6th and clutch will be heard/seen slipping..

Again this is an example of a clutch almost on its way out..not completely finished..
