Nf Governor

I might be mistaken but some of the info on this subject is not quite correct-as I understood,the Nf governor is only active in the beta/reverse range.how does it govern any forward trust? This governor is a integral part of the Primary Governor,it consists of a reset arm,bleed link(which could be a rigid or lostmotion tube).The reset arm is connected to the reverse/beta cable,which is directly contolled by the beta valve activation.This is motion is controlled through a cambox arrangement activated by the input arm connetced to the Cockpit contol.Once the reset arm is moved from the min. stop it bleeds modified Py pressure off,this then resets the fuel flow on the FCU. and actually not controlled by oil pressure.The oil pressure has only and effect on the parameters once fuel schedules have been adapted.Is this correct?
