I am assuming upfront that there is no megacursed strat for min primary to get below this value, though without one being involved I don't see why we were given the triplex bonder, so... just going to pretend the puzzle is kind instead. 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 leads to all kinds of collisions w/ a length 2 arm on the top, and other lengths aren't compatible with proliferation. 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 (assuming it is 2 arms + track), it's kinda whatever.
