Having spent about 5 years as a member of energyresources list I read a lot of Mike Lynch's 'stuff.' One of the most notable interchanges was on the subject of creaming curves, between Lynch and Laherrere, the upshot of which was that Lynch had no real idea of what a creaming curve was. I recall that after that episode he didn't show his 'face' on the list for quite a while. I don't have any respect for his ideas. He is not IMO the least bit rigorous or scientific.
In order to learn, what is a "creaming curve".

I have had some training in statistical analysis, but I am unfamilar with the concept.

Thanks,

Here's a good description that even a nitwit like me can follow.
