I've thought about this a little more and it's starting to make more sense. The fact that they give me two sets of shift points indicates that there really isn't one good answer for "when do I shift?" It depends on how fast you are accelerating. If your rate of acceleration is glacial, it stands to reason that you could keep the revs under 1800RPM without the engine protesting, since the load is so ridiculously low. At faster rates of acceleration (higher engine load) you need to let it wind up a bit more so that it can produce the power that you are asking of it. So I guess that's just a whole lot of words for what we all think of as common sense. If the engine is struggling the gear is too high or your foot is too heavy. Maybe we need to add a new acronym: SWEL = Shift With Engine Load. Don't confine yourself to a single shifting pattern, but adapt to the rate of acceleration that is required for a given situation. What do you guys think? We're just over-complicating the obvious, yeah? It seems important, though, since experience tells me that finding the right throttle position for a given speed and gear can be very touchy with respect to FE, and I may be driving around in entirely the wrong gear a lot of the time.
