Memory Reservation for View Desktops

"Set the VMware View Master Template with a 50% memory reservation so all VDI machines deployed have a 50% memory reservation"

Is anyone else doing this?  My template is currently set to 0 for the Memory reservation.

My current setup:
Windows 7 x64
2 vCPU
3GB RAM

So I should set the memory reservation to 1536 and test?
