Resource pool reservation/expandable reservation

I have 24GB of RAM available at the cluster level (there are 3 hosts). I created two resource pools and called them Development_VMs and Production VM's. See screenshot for settings.
Note how Expandable Reservation is enabled. I understand that this is to satisfy virtual machine-level reservation set within the resource pool. Questions:
1. How is the used reservation = 576MB? I added up the virtual machine overhead memory and it comes to 300MB, there is no reservation set at the VM level so how is it 576MB? Is it some other kind of overhead?
2. I realize I have Expandable Reservation enabled, how did it calculate that the available reservation is 9341 MB? I have 24GB RAM at the cluster level and the other pool (Development_VMs) has the following config:
So I guess the question is how it arrived at 9341 MB? Configured RAM on each VM is (AppVM2 = 256MB, Dummy = 4GB, VM1 = 256MB and VM2 = 4GB)
Thanks!

Expandable reservation allows the resource pool to borrow resource from the parent cluster/resource pool. As for the 576 MB resource used, did you add the CPU & memory overhead?

That might be it but how do I find out the CPU overhead?
