The car would rock/shake a bit as the DCT was engaging and measuring the clutches during the procedure.
Personally, I run the clutch adaption routine every 15K - 20K miles so that the DCT can optimally use the current state of the clutches. Having driven a manual for 19 years, I would alter my use of the clutch pedal based on the current thickness of the clutch. Thinner DCT clutches without proper calibration naturally leads to more power being applied before the optimum contact and friction point during a gear shift or launch. It's like giving it too much gas before the clutch starts to engage which can lead to either advanced clutch wear or too much slip. This, of course, is only during gear changes. The fact that the DCT can vary the line pressures based on clutch thickness can help with holding power while in gear. Please look at the before and after clutch adaption pressures in the pictures. They went up after the adaption routine.
I am not stating that running the clutch adaption routine will fix your slipping clutches. I am stating that you can run the clutch adaption routine by yourself with the Schawaben scanner and not need an indie or dealer.

This is what I thought Bimmergeeks Protool did but unfortunately not. It only reset adaptation but haven't the clutch service/teaching function implemented. Tad dissapointed...
