I spent a lot of effort on this submission. My best solve was using just one tarc for half the week, at around 320. Then I finally broke through by starting from my simple 50 Cycles layout. Within just 2 hours, I brought my score all the way down to 228. My girlfriend widely underestimated my potential :3 It seems like this layout has a theoretical minimum of 219. Hot take: I think that the top solves will use just two tarcs.
