@ Ali : No Ali, as I have stated, in high paging zones , keep MFRMS relatively higher like 5 or 6. Please note if you set the value too low like 2 , it could lead to queuing and hence paging discards.
Note : High traffic, high MFRMS!*
* : Also subjective to other parameters like TX Integer, AGBLK, T3113, IMSI Detach etc.
