Sn nhs
nhs: Value of (nds + (20 n4))/(1488 Sn) rounded up to the nearest integer
Sn (RXb + RWrb) + Ln (LBxmb + LWxmb) + Sn
RXb: Value of (Total number of points of "RX setting" of main modules)/(11744 Sn) rounded up to the nearest integer
RWrb: Value of (Total number of points of "RWr setting" of main modules)/(734 Sn) rounded up to the nearest integer
LBxmb: Value of (Total number of points of "LB setting" excluding master station)/(11744 Ln) rounded up to the nearest integer
LWxmb: Value of (Total number of points of "LW setting" excluding master station)/(734 Ln) rounded up to the nearest integer
