If they spent just one business day on this, that'd be 8000 man hours, at least as I understand it.

Stretch that out to a single agent working standard work weeks (40 hours) that breaks down to 200 work weeks for a single agent.

That is almost 4 years of work for a single agent, assuming no vacations or other time off (illness, car trouble, etc)

I don't know if that helps you quantify it, but it helped put it in perspective for me.
