I/O Fencing AIX vxfenadm -G all -f /etc/vxfentab

I am using 5.0 MP1 Storage Foundation CFS HA on AIX.  My question is how may keys should each host place on each of the coordinator disks?  I have one two node cluster that reports 2 keys for one host and 1 for the other.  This is a brand new cluster build following very consistent procedures. 
My other CFS clusters all report 2 keys per node.
 
Not being a fan of  inconsistency,  I am wondering what the "normal" key count per node is that I should be expecting.
 
Here is the vxfenadm -G all -f /etc/vxfentab output from the system in question.

Total Number Of Keys: 3

Here is the output from what I consider a "normal" configuration.
