GLM is advanced and robust measuring-AI, outperforms 99% of REW + UMIK -amateurs on machines cold routine: it uses calibrated mic, its measuring routine and measurement interpretation are bullet proof. It wont make stupid, amateurish human errors.
No human errors means in practice: GLM´s mouse hand won´t begin to shake and lower lip to tremble in uncertainty when it tries to google / search from internet forums how other amateurs have set their filters.
So, you should just trust GLM´s judgment. It´s most advanced measuring-AI available. Your job is only place mic properly, run AutoCal and stay away / silent when GLM measures.
Serious question: Do you understand what GLM actually does? Because the above sentences tell me that you don't understand, you just think it's a magic solution that does magic things. It's not. GLM is effective but it mainly just applies simple notch filters to reduce peaks below the transition frequency. It does make some other small adjustments with shelf filters and such sometimes, but it doesn't all-pass phase the way Dirac does(whether that's useful is another story, but it doesn't).
GLM still doesn't appear to have anything like Multi-Sub Optimizer. So it's not "the most advanced measuring-AI available".
I get the feeling you signed up here just to evangelize GLM, which is really silly, it doesn't need that. I appreciate you pointing out the release note, but it does not seem like anything significant HAS been changed at all, so, GLM is still well behind MSO and DLBC in terms of bass management capability.
