Exchange 2013 Calc Question on Input Page?

Hi All,

Its more important to me, please some one help me on this.

We are planning install Exchange 2013 MultiRole server on VMware.

I am using Ex2013 Calc for sizing the hardware. I have the Physical server Core Details and SPECInt2006 rate value of the server. 

I have gone trough the below article it says if we going to deploy exchange server in Virtual then we must use the below formula to calculate the CPU and enter core and SPECInt2006 value on Input Page.  is this correct?

if its is correct then what is the purpose of the Role Requirements Results Pane page.Here below i have taken some example of Serve core and SPECInt2006 Value. It shows if i give the Physical server(VM Host) Core and SPECInt value in Input page it give me the Output on  recommended Number of Core per server is 6 and all looks good.

If i follow the formula then it shows very worse. Please let me know what data i have give in input page (Real Host Core and SPECInt value or I have to use the below formula and give the input).

Please don't share any article i have gone trough many articles....

X/(N*Y) = per virtual processor SPECInt2006 Rate value

Where X is the SPECInt2006 rate value for the hypervisor host server 
Where N = the number of physical cores in the hypervisor host 
Where Y = 1 if you will be deploying 1:1 virtual processor-to-physical processor on the hypervisor host 
Where Y = 2 if you will be deploying up to 2:1 virtual processor-to-physical processor on the hypervisor host
