Being an engineer myself, it's very easy to spot that.

Your really trying to discuss three things;
Roll centre
Static camber
Camber gain

Now static roll centre position does have an influence on camber gain, as the link posiitions are used to calculate it. Changing your camber gain settings WILL alter your roll centre position. There are no two ways about it, as they both rely on the link angles. Static camber will not however influence roll centre, so the two can be considered mutually exclusive.
Now I mentioned before, the calculator is a guide, nothing more. Its there to give a comparison on settings, mainly as it only calculates the STATIC position only. There's no way I have the time to make one up to calculate the dynamic roll centre.

Your doing the same thing you did before with the flex topic... Trying to compare the real world with the small world, and completely forgetting about scale effects. You mention about audi's and subaru's in a previous post, but I very much doubt any of them would be able to top out at over 300mph, let alone corner at that speed.... Something else to bear in mind is that link positions are a lot easier to change on our cars, as we don't have to redisgning mounting points etc.
Instead of bagging the change as pointless, think of it as another weapon in the arsenal. I guarantee you'll feel a huge difference to the car.
