With this submission, I believe I understand the metrics. Forexbax Zengaxovovoz means "Movement Instructions," which is the total number of instructions excluding arm rotation and pivoting. Xal Zengaxovovoz is "All Instructions," and simply counts the total number of instructions in the tape. Xiro is "Area." Griix Zrops means "Earth Grabs," and counts the total number of times an earth atom is grabbed in the simulation. Vuip is cost, and Myssis is cycles.
Every metric is then multiplied by (2 + # of reagents placed).
