There are multiple items here that aren't directly related:

1. The DNS test page reports times for configured servers which doesn't care about resolver or forwarding mode. I'll add some notes about that to https://docs.netgate.com/pfsense/en/latest/diagnostics/dns.html but haven't done so yet.
2. There is no document explaining the process of DNS resolution in general -- This is now covered by the new document at https://docs.netgate.com/pfsense/en/latest/services/dns/resolution-process.html -- but it is not specific to the DNS resolver so it wasn't in the DNS resolver documentation before, and still isn't now. It's in the DNS documentation.
3. Issues with resolver mode and multi-wan -- This is already noted in a few places around the documentation, such as under Multi-WAN at https://docs.netgate.com/pfsense/en/latest/multiwan/interfaces-and-dns.html and is mentioned in the DNS resolver configuration as well. I've updated this a little and it's now under https://docs.netgate.com/pfsense/en/latest/services/dns/resolver-modes.html but it was previously on the main page of the DNS Resolver documentation.

Additional updates:

1. Added a new section to the DNS Lookup page which describes how it selects servers to test.
https://docs.netgate.com/pfsense/en/latest/diagnostics/dns.html

3. Cleaned up and expanded the Multi-WAN DNS information on
https://docs.netgate.com/pfsense/en/latest/multiwan/interfaces-and-dns.html

Also as a dependency to the above, I updated the documentation for System > General as it also influenced the content of the other updates.
