You do not use cruise control to bring the car up to speed.
The purpose of the +/- is to bump cruise speed up/down while in cruise to adjust speed according to traffic etc.
Get the car up to cruising speed with the accelerator pedal, engage cruise and adjust as required.
As for fuel economy.. There is no fuel saving potential in a high rpm race to cruising speed. None.
Note that being aggressively gentle and taking too long to reach cruising speed is also detrimental to fuel economy.
The most efficient form of accelleration is a balance of reasonable throttle vs time getting to cruise speed.
I'm in my second cvt Mirage and I use cruise at every opportunity. I see very good economy numbers without much effort.
The cvt trans is nice in that you can hold the accelerator at a specific rpm and allow the car to cover a very wide range of speed. Personally I try to keep rpm around 2100 or less in cruise and I +/- as needed to maintain this as an average, around 60 - 65 mph.
For me acceleration to cruise is handled by holding 2500-ish rpm until 60mph then on cruise.
If conditions require it, I run rpm up to 3000-ish to get there. Rarely will I accellerate at higher rpm unless passing or getting out of the way.
With this method I get daily average commute economy (avg. of both directions) which right now includes detour on gravel country road, highway and rural 60 km/h road of 4.7 to 4.9 L/100km. Total daily commute is 55 miles on average.
