Clarification about the "default" option in a DHCP scope

[firsttiger]

I'm very interested in moving from my Technitium solution to Gravity as I think it's a better fit for me. I've done a quick install and I wanted to clarify the functionality of the default configuration in the DHCP scope. I've read the documentation found here: https://gravity.beryju.io/docs/dhcp/scopes/

Let's say I have the following scopes:

default
range start: 192.168.1.200
range end: 192.168.1.253
default: checked off

main
range start: 192.168.1.100
range start: 192.168.1.199
default: not checked off

Let's say I have a new machine come onto the network, is it fair to expect that the new machine would take the IP address of the default scope?
