vSAN capacity - vsphere vs document discrepancy

Hi there,

I am looking at the space requirement for a 100GB VM in a vSAN environment, how much space does it actually consume, according to this article here:

https://docs.vmware.com/en/VMware-vSphere/6.7/com.vmware.vsphere.virtualsan.doc/GUID-AD408FA8-5898-4...

Running raid 5 with PFTT of 1 require 133GB; raid 6 with PFTT of 2 require 150gb.

However when I am looking at my own environment, when create a new vSAN storage policy, Raid 5 and 6 showing that it will consume 200gb and 300gb respectively, i have screenshot here: https://imgur.com/a/HpOUQcj

Am i missing something here? 

thanks,
