"Start with optimised RPM". That is quite punishing to the brakes and will wear it off quickly since we need to press on the brakes AND the accelerator at the same time I guess, before we release the brakes as the car leaps forward at the touchline. Guess that is how a faster 0-100km/h time is obtained, instead of launching it from zero RPM.

If you really feel the jerking on your own, and as per what the others says, the car feels like leaping forward.
It feels like releasing the clutch too much on a MT without stepping enough on the accelerator.
There's no jerking if u floor the accelerator.

For me, there's only a specific zone in the accelerator that will cause jerking.
If u challenge the system and like to always hit on that specific zone then sorry lar.

I am not really good at car stuff but this is the gut feeling based on my 5yrs MT and 5yrs AT driving.

This is the theory of my own:
I think the reason for jerking is that dual clutch is shorter that convention clutch.
Shorter clutch are used in performance clutch, shorter clutch losses less power during transmission.

Compare to others car that the AT is very smooth, it is because the clutch is longer.
Longer clutch allows the flywheel to have more time to break inertia even when u r soft on the accelerator.

Make sense? to me at least

About changing the driving style...
You're not going to drive an F1 race car just like how you'd normally drive right?

That's the price you pay for the efficiency of a dual clutch transmission. It is different from traditional torque converters for sure, it is more sophisticated and more temperamental at low speeds.

If you are used to a torque converter auto and worry about the eccentricities of a dual-clutch drivetrain, I can only advise you to think long and hard before making the jump. It will never be as comfortable as a torque converter when going slow or going up slopes, you will no doubt need to adjust the way you drive. If you cannot accept that, then go for something like the new Mazda 3 that is almost as nice to drive but comes with the benefit of a torque converter.

Choose the Focus ONLY if you are looking forward to superior driving dynamics and driver's enjoyment. If you're looking for passenger comfort and cares not so much about driving, an Altis, Civic or Mazda3 is a better choice

It's understandable. I've driven the normal torque converters, CVT, now the dual-clutch.....they all have different characteristics that needs to be adapted to with different driving styles. That's why I always say, don't blindly jump on the bandwagon because you heard Focus handling how good the dual clutch how awesome, it's not suitable for everyone. If my dad drives my car in a jam he will curse it to heck.

But if you're like me, you will get used to it soon and can naturally compensate for the eccentricities without giving much thought to it. At one point I was switching between an old 4AT, a CVT and the DCT regularly and didn't think much about the differences, my feet automatically just knows which car I'm driving and adjusts accordingly

What's your mileage now bro? Ron97 price just went up another 5 cents while the global market price went down, our government are getting poor.

You're lucky to get to drive from the age of 18, nice.
No need to remember once you're familiar, we're all spoilt thanks to the P1 and P2 and the Japanese made car. Imagine if we're raise up with an European car, we might think the Japanese car are boring to drive, lol.
I think your theory make sense, I never drive a MT before (except during license taking),  but I think it's quite logic if you give it a thought.
It's not a temporary workaround, it's a permanent solution, to adapt our driving behaviour to the CHARACTERISTIC of the DCT.
Really? I should start to give it a try then, could you also monitor your mileage with S mode?
I afraid there's none, there's really not much ST in Malaysia.
Why peoples keep forgetting about SAFETY, lolx, I'm really surprised with what's the first factor that comes to a Malaysian mind when choosing a car, looks like it's not the safety but the transmission, that's shocked me!
Then I afraid you have to looks else where (maybe in our dreams ) , there's no such thing as PERFECT car in this world, in fact, there's nothing PERFECT in this world
I doubt there'll be any face lift this year, maybe next year.
