Standard service volume is 8 deg L/RCL and out to 10nm (from the GS antenna).
On an unrestricted facility, as you come around the corner you should be getting useable GS information to use as a reference.

This service volume closely equates to a commissioned VGSI's unrestricted service volume too.

So both can/should be used as references as well as an eyeball calibration looking outside in a visual landing pattern.
