Yes, that looks broken. I need to go back to the drawing board on the formulas for subscription models. It's a very rough cut that clearly needs some work. I'll try to get an update done with a better model in the near future.

To be a little more clear: Max VM is used for calculating Avg, so that's why it's '1' on the baseline. The Avg can only ever be '1' if there is only one VM on the physical host.

Thanks for identifying that. That is actually intentional. I apologize that it's confusing. I'm trying to show a 'baseline' in row 6 where we allocate a single VM to a physical host for comparison. That's why there is a box around it. But it's definitely not as clear as it could be. I should pull that line out of the table and put it elsewhere and explain that it's for comparison.

And there`s something i don`t understand in Row 10. How could Avg Core Usage per VM be 2.00 while Min and Max both are 1.00?

I though there`s a mistake in your Excel spreadsheet in F6.
The number of MAX VMs should be 16.
