I gave this a cursory look and I'm going to guess that there's "no there
there". I suspect the point-values are hard-coded, and that somewhere in
the code a developer just typed in a sequence of numbers that felt right.
The first differences are encouraging at first: 37, 46, 55, 62, 67, 72 ...
but if you look at the second differences they seem kind of random: 9, 9,
7, 5, 5, 4, 6, 1, 2, -3, ... so the first differences aren't even
So I think your expectation is correct.
