Since I raced a 4-speed car for a few years, I'll take a stab at this one.
You experiment with shift points, til you find those which produce the lowest ET. Without actual, on track testing, all you have are opinions. And, as we've seen on this and most every forum, opinions can differ WIDELY, on most any given subject.
There can be too many variables with engine & cam torque & power numbers, trans & rear gear ratios, etc.
