Venus Versa for fat reduction/skin tightening treatment?

I recently did only ONE treatment of "Arm tightening" with the venus versa machine, that offers radiofrequency. In the middle of the treatment, the provider had to switch with someone else and because it was two people, I am concerned now that the treatment was NOT done equally on both arms, as maybe one arm may have had more fat cells killed than the other with more spent more time on one arm. My question: should I be concerned for disproportionate results? I am only doing this one treatment.
