Cost of developing 1 hour of elearning

So - if I'm understanding Chapman's presentation - the average development cost is a little over $100 per hour.  I appreciate that different people, contributing different elements to the team effort may have an hourly rate above or below that, so...

everyone - Is USD$100/hour fairly consistent with your experience of usual and  customary billing rates?

Please say: "It depends."  ....

Thinking about Sean's original query here - when asked: "How much should we be paying for an hour of elearning?" - would folks generally feel comfortable saying something like this?:  

"Industry research suggests that a basic, but professionally produced, hour of eLearning requires about 185 hours of effort at an average cost of about USD $19,000.  But the reality is that price varies a lot.  Costs can be lower if the hour doesn't involve any interactive learning exercises or higher if it includes higher-end elements like simulations or games."
