Mike, the improvement might not be linear. The diminishing return will kick in and we will not see such dramatic difference like that in the future. We can use racing as a good analogy. When we first start sim racing, we are usually very bad and crash everywhere. once we learn the basic of braking, we sudenly improve our lap times a whole lot. However, to drive to the limit from that point, it will take us a longgggggg time because diminishing return effect kicks in.
