Exactly right. However, once the CG is worked out for the flying, the gear might have to be moved for the ground handling.

BTW, the CG trimming tests are pretty much exactly like the landing trimming test. You do something with the plane that tests pitch recovery and that tells you where the CG is for flying. You land the airplane and how it reacts upon hitting the ground tells you where the gear needs to be.

There are many ways that the gear can wind up "in the wrong place".
