Taking a step backwards a bit, I added some measures of how much tension the pitch is creating throughout the lick. For example, Lick 0 is:

And plotting tension through the lick, I get:

The exact amount of tension each pitch creates is debatable and not so important at this moment as I'm more interested in having this kind of measurement infrastructure in place.

Valuse of tension from the root are as follow:
tdic={ 0:0, 1:11, 2:4, 3:7, 4:2, 5:5, 6:10, 7:1, 8:9, 9:3, 10:8, 11:6}

If someone has another idea of what the tension values should be I'd love to hear about it. I haven't found much that quantifies this.

I generate a bunch of different metrics, I image the tension integral and tension integral average is most relevant. The total amount of swing in tension is also interesting, I'm calling that sum delta tension.

Here's an example showing how the M3 releases the tension form the piece of the min7 chord.

A lick ending with a fair amount of tension.

The tension is held through rest notes.
