different rpms in C vs S modes

I have a question, when the car is in C mode and switches to S should RPMS rev higher? when is S+ and Race mode engine revs higher ( can be seen and felt )
Thank you!

Yes it does, but not nearly as high as in S+ or Race.
However if you have been driving about lazily, you won't notice much of a difference in shift rpm between sport and comfort

That is true, the transmission is constantly learning driving habits.

If I’m sitting in park, and switch from comfort to sport+, my idle rpm increases. So yes that is normal.

Does the transmission learn per key? For example if you drive with the main key does it adapt a set of driving habits but if you drive with the spare key it then adapts again thinking it is a different driver?

Are you talking about the idle rpm? If so, no. 99% sure, but I don't use Sport very much. In Sport+ and RACE, the idle rpm is several 100 rpm higher. If you are talking about while driving, then yes, Sport holds the gears slightly longer than Comfort, so your average rpm will be higher. Sport+ holds lower gears even longer and so does RACE mode. But as said above, if you drive casually then even Sport+ starts shifting to higher gears.
