Definitely left refinement too late this week. I thought I could get min secondary fairly easily, especially after the bottom half worked out really nicely, but making the narrow V first means that having a length 2 arm at either of the further locations results in hitting itself when trying to make later bonds, and the inner locations fail due to either input collisions or output collisions. Took my length 2 solution and adjusted to length 3 using some track, just so I'd have something I'm relatively happy with. And yes, the tertiary clearly wasn't the priority in optimising, which concerns me given that that seems to be where the race seems to be, but given that I'm not at min secondary, it's kinda whatever. There better not be some cursed strat that makes min primary be lower than this, same with the possibility of min secondary somehow not being 2 arms.
