yup. they're all about motion by the looks, and that's the "title" of it N2 of motion. The tweaks that the maestro was referring to are at HIGH speeds, or at lower speeds if you fancy (I don't personally) going to several decimal places in the calculations. That could apply to B. Depends on how "awkward" people want to be (very sometimes ?)
