fold back assistance ADM1270ACPZ-R7


I am after some assistance with this hot-swap controller, in particular, the setting of the foldback resistors. 

I understand that these are there to keep the FET within SOA, can someone please go through the process of specifying these?  

The  parameter for the circuit are 
9-30V input 
~4amp over current protection.

Cheers Clancy.
