Thanks bro...my advice to always control our right foot to rev bet 2k-2.5k rev & between 90-95km/hr during overdrive should achieve better FC 
Yo
Ya, 2000rpm can enjoy 100km/h speed for CVT. You are very right.
But,
If i am going to KL, sure speed one. When speed, will accelerate more.
But again,
You are right also, must control our right foot, because for CVT, we can slowly accelerate if there are no cars right in front of us, by slowly accelerate from 2000rpm (enjoy 100km/h) then slowly accelerate to 120km/h, that shld be able achieveable at 2200rpm or slightly more rpm. To enjoy 140km/h to 150km/h, i think 2400 to 2800rpm can hit liao!!! Still good FC at the end!!!
