So, the list is only those pairs that made it through the processing.
Would have been better if I had also weighted using his approach, as pairs like "theater theatre" end up on top.
Still interesting though. It found these, which I liked:
0.33 swinger wingers
0.33 parrot raptor
0.33 borsht broths
It's flawed too, but does put some good ones at the top.
