Heavily related psalms

Here are pairs of psalms that are more strongly related - sharing >= 5 words per verse.
Psalm 14 and 53 we would expect. Psalm 136 will be high with any psalm mentioning mercy. Psalm 150 has some very high relationships with Psalms 113, 146 and 148 - all doxologies. I have not yet mapped Jinkyu Kim's suggestions (SBL paper on the strategic placement of royal psalms) - but these doxologies seem not out of place.

The score means x words per verse match - the greater of the verses for each psalm is used in the divisor. Some day I will find a way to summarize this in a single picture - but for now there are too many points 150x150 to fit conveniently anywhere all at once!
