I'm afraid that I don't think in numbers and number patterns, so I am not much help.

I learned music theory and practice, and if I need to play an Ebm9 chord, I just know exactly what notes to play without counting intervals. You should practice like that too. But I somehow guess you are more focused here on how the bass interacts with the tonic chords.

I see a Gsus4 in bar 4, which could also be interpreted as a Csus2, depending on other parts of the chords structures. In your case, highly likely to be a Gsus4 because of the basic 1-6-4-5 chord sequence you have used.

Now, sorry, what was the question?
