I'm kind of late to this topic, but I thought that when the DO's were cut that there would be some kind of downsizing of CO's. The problem though might be that the CO's are now the "Company Men" for the Borg. The CO is who audits the BOOK$ and handling of the FUND$ in behalf of WT. They also inspect the condition of the KHall to see that WT's investment is being maintained in top shape.
Currently, CO's make two visits each year to each Cong. So, I think they could cut the CO's by 50% by only having ONE visit per year by the actual CO, and have a sub-CO (or a CO-wanna-be) from the circuit (or better yet, a nearby circuit) to do the other visit. Congs would still pick up the expenses of the sub-CO, but WT would not have to provide healthcare to the CO & COW (big issue in the USA). With this in place, a CO could now cover twice the number of Congs.
Remember, you heard it here first!
