There's always a hierarchical structure on elder bodies. Normally its the COBE on the top and he has minions that rank in subsequent order the rest of the service committee usually falls in the top 3 or 4. The rest of the elders are "bantha fodder" and have no real power to speak of.
The CO comes in and gets the scoop from elder 1-4 early in the week then puts on a pretense of an elders meeting with all the elders on Friday to "discuss" issues and appointments even though every decision has been predetermined.
I can almost guarantee this is the formula for most elder bodies and CO visits.
