I've extracted this form the link you've pasted..and the research that they have made was not concentrated on CVT.
On the other side, we have CVTs - continuously variable transmissions. Using novel technologies, these can vary the gear ratio such that the engine always runs at the same speed regardless of the speed of the car. In that case, design of the cam will be very simple. Since power can be freely adjusted, you don’t need a wide power band.
There are huge difference between CVT and the conventional auto transmission.
CVT is based on a coned shaped pulleys and a metal belt that runs between them that slides between the narrow and wide end of each pulley. When the belt slides, it allows continous variable gear ratios without any gear being changed.
The normal auto transmission consists of gears, friction plates, hydraulic fluid and a torque converter.
Anyway, you can't make a comparison between the manual gear and CVT....simply because CVT is an alternative for the traditional automatic transmission system. Clearly there would be power loss when gears are being changed as opposed to CVT even you were to close the ratios of each gears and CVT is not an option for performance based cars.
