HA Slot Calculation for vsphere 5.x

Let us say we have 2 ESXi hosts
RAM per ESXi host is 16 GB
CPU = 4 core X 3.4Ghz

CPU Total Capacity is 23064, divided by 2 nodes = 11,532, divided by 32MHz = 360 Slots
RAM Total Capacity is 26731, divided by 2 nodes = 13,365, divided by 53MB = 252 Slots
Can’t have CPU without memory so the max would be 252 HA slots.
