Re: CVT, which teams are planning on using them for next year?

I see what you're saying NoodleKnight, about how a driver has more difficulty and how it's harder for like, 4 speeds and how it may seem impossible for a CVT by just pressing buttons. A 4 speed shifting gearbox has 4 buttons for the different speeds. For a CVT, really, you should just need two buttons to control the shifting of it. One to gear it up gradually, and the other to gear it down. You could probably just use the buttons on the joystick to do that.
For a Variable Pulley Diameter System, you could design it in a way that the two pulleys change diameters together, so that when one pulley diameter increases, the other will decrease accordingly. This part could be done by programming, so you are right that it can be done automatically and it would be easier for a computer to control it, but it could also be done mechanically. For the changing of the gear ratios can be controlled by simply pressing the left button on the joystick or the right button on the joystick to change it. If it's that simple, I really don't see much of a need for the programming to control the gear ratios.
So overall, computer control in a Variable Diameter Pulley is a good thing to control the 2 pulleys accordingly, but it is not needed if a driver could do it with just pressing one of buttons that he can easily reach and get accustomed to, probably in just a matter of hours.

But then for this type of CVT or another type, how would you program it to get the maximum efficiency out of it?

...That's just my two cents.
