Jimlad,
The pay scales showing non-X factor pay certainly relate to Full Time Reserve Service personnel in the RN - not sure about RNRs, TA etc - but basically, if you're a full time CPO/WO/Lt/Lt Cdr etc working on FTRS, you're paid the full time normal service pay minus the X-factor. As we have quite a lot of these non-deployables past normal retirement age, they actually publish the tables for all to see - so those receiving it know how much they are going to get and so that PAS knows how much to pay them....or JPA does not as the case may be at the end of this month....
