What does firewalling a performance review mean?

All the scores are at the max. "Firewalling" the throttle means full power (pushing it towards the firewall).

Firewall fives, I forgot about that, or maybe blocked it from my memory. It’s the same for enlisted.

No kidding, my first EPR out of tech school had a bunch of 4s and when it came time to test for SSgt my combined points were so far off I just gave up and coasted until I got out. For the best though.
