To be fair, the report explains their reasoning: they state the mean is too sensitive to outliers.

Now, I do agree it would have been nice to demonstrate this, however it could be genuine.

That's a complete cop out. They didn't give the data to back this up.

They definitely should have shown an example, or referenced something else that backs up their claim. I think it was you who made the good point that, when it comes to data usage, the mean may well give you more meaningful information because of the outliers!

I can see the median being useful for answering what the cost of one more server/agent/whatever would be, but that’s not what this paper is asking.
