Psalms compared in sequence

I did some rather random work 5 years ago in the stretch to learn letters. How do psalms relate to each other. One possibly interesting question concerning the thesis that the psalms are a Book intended for sequential reading, would be to examine the shared vocabulary between consecutive psalms.

So for instance, (apart from the very common roots: על יהוה  אל סלה כי אלוה את)

Psalm 2 with 92 words uses 9 words from psalm 1.
Psalm 3 with 70 words uses 9 words from psalm 2.
Psalm 4 with 77 words uses 17 words from psalm 3.

Clearly psalms 3 and 4 are much more tightly tied to each other than psalms 3 and 2.

Psalm 5 and 4 are related in a clear pattern - curious.  These 3 are all psalms of David so I wonder if we might see expect some patterning.

Psalm 6 we know is different, being penitential, and the pattern also changes though 16 of 84 of its words occur in psalm 5.

In psalm 7 (15/142) we are back down from the 20% range to the 10% range.
