This is one of the two JPL5, the first one discovered. Later study discovered
As per description on MAIL this is made from 72 (288) degree steps. The other is made from 144 (216) degree steps.

For JPL 7, there's 3 different versions; 52(308)-step, 103(257)-step and 154(206)-step.

General formula is JPL(#): (360/#)*n, not regarding flipping the weave to fit the lean, as (360/#)*n gives an equivalent angle at (360/#)*(#-n).
