RSOP support has been deprecated. According to http://deployhappiness.com/gpresult-or-rsop/
"Beginning with Windows Vista SP1, Microsoft made the GPResult command
the primary tool for troubleshooting Group Policy on a client."
Basically, to ensure that you are getting the full result of policies on the machine, you need to use GPResult instead of RSOP.
However, your account is located on the Domain Controller, and therefore, the policy of the Domain applies to lockouts. No amount of tweaking, configuring, or policy editing will change that on your local workstation. Any time you enter your password, the Domain must authenticate it, and it will count towards your attempts. Other things can count against your attempts as well, such as cached credentials, or being logged in to other computers with stale credentials.
This part is no longer relevant.
Furthermore, the location of the account is incredibly important!
If the account is actually an Active Directory Domain account, your local machine policies will NOT affect your account lockout,
you will have to check the group policy settings of the domain controller (e.g. run GPResult on the DC). Accounts stored on the
domain don't authenticate against your computer, and the lockout is
triggered on the domain controller, not your local workstation.
Accounts stored locally will follow the GPResult, but only after
you've rebooted the computer since the WinLogon service will have to
re-initialize with the new GPO settings. (Not all GPO settings can be
applied without a reboot).
