Yes it is and thanks very much. Just FYI there is no need to explain the actual physics, having built cars and raced cars and bikes and having been a student of motor racing all my life, I understand the real world very well, just not clear on how it is represented in the sim.
Thanks again, making more and more sense every day.
As an educator myself, I understand how difficult it is to teach stuff you know intuitively; trying to formalise 25 years of management consulting into training courses was a lot trickier than I thought it would be. But as I often said to students, the real test of your knowledge is whether you can teach it...
