FastCGI MaxInstances setting

First, I've noticed that the documentation suggests setting the FastCGI application MaxInstances to 0. When I attempt to make that setting, I get a response stating that MaxInstances must be an integer between 1 & 10000. Is there a way to set this to 0 without
manually diving into the ApplicationHost.config file?
Also, what are the implications of setting this too high or low? I've seen a number of performance sites suggest setting it to 1 to manage CPU load, while others suggested 10+. Microsoft defaults the setting to 4, so I was wondering what the implications
of this setting are in relation to visitor and CPU load.

Take a look at this:
The value should be set according to the number CPU cores. Approximately 8-10 per core.
