FWIW, I think I collected all of those charts here. They're:
- (not sure. Left axis is HP, bottom axis is RPM; they could be comparing the output of two hypothetical motors)
- torque and hp of the two different cam set-ups in the VV motors
- result performance (in red) by switching between / using both sets of cams
- valve duration / lift / overlap from the two sets of cams
