This is one of the two JPL5, the first one discovered. Later study discovered https://www.mailleartisans.org/weaves/weavedisplay.php?key=1434
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).
