I think is a good quality but RMS is out of standards

You can send a short test to ACX before you read a whole book.

That and the sample has to conform to their technical standards: Peak, RMS, Noise.

When you apply Limiter, remember to change the limit setting to -3.5 rather than the default -3.0. If you leave it 3.0, you have no room for error. Any mistake and the work will fail standards.
