S and L hold a higher base rev, with a much stronger engine brake; L holds a much higher base rev. The "false shifting" at high rpm is to maximize power, as power drops over the peak curve, so it's still doing its job in maximizing power. Holding at 6500rpm doesn't result in the best performance between 45-80+ mph, as power would drift and drop as acceleration occurs. Dropping rpm to pick up torque over the rpm curve makes complete sense when operating at the top of the curve, hence the "false shifting". Something you don't see, but is also happening at lower RPMs, albeit much more quickly. From 0-45 it will hold the peak torque/Hp curve around 6000rpm, but once it reaches the critical point (speed, acceleration, torque, v-tech), the CVT adjusts to continue maximizing power to the wheels as efficiently as possible. Above 100mph it gets pretty interesting when v-tech is perpetually engaged up to and over 100mph. Between vtec, cvt, I can definitely tell you it's doing its job up to and over 135mph.
This is exactly right. There is no "false shifting": it is real "shifting" which is in fact gradual as it should be, just fast, and to any ratio that could be appropriate, not necessarily to any preset ratio. If it was slow, the complainers would not talk about "false shifts" but about the CVT being slow. It's just CVT doing its regular job of an atomatic transmission optimizing the output ratio to the conditions of available torque, moving resistance and current road speed. This falling back is a direct result of the shape of the power curve (having a maximum). Who says that a CVT will not need to dial back the "gear" but just has to or even can keep going higher and higher? Specifically, it is dialing back the gear ratio to avoid "lugging" the engine as the torque eventually drops while the resistance increases with the foot to the floor. This would not happen on a flat road if it was a CVT CTR.

YOU got that right! : )....Honda please "gimme" one of those CTR w/CVT.
