SculpSure are 2 applicators not as effective as 4?

Is it true that if you only use 2 applicators for a treatment of sculpsure it's not as effective as all 4? As in the power is being wasted and you wouldn't being getting the full power since the power is supposedly being distributed thru all 4 applicators every time the machine is being used? That is what I've been told by one nurse. She said it's weird that only 2 applicators were used per treatment and that energy was being wasted and I wasn't getting full effect.
