I think this is as fast as it can go. Since the output contains 7 atoms, and since 7 is prime, you can't build this in chunks by attaching things to the central atom without making waste or needing to do weird unbonding things. Since the last atom you pull must be calcified, it has a latency of 2 or 3 (I dunno how this is counted lmao, imagine me actually learning this theory), so I believe 84 is as fast as it can go. Knowing this community, however, I am aware I will be proven wrong, because that's how it usually goes!

Side-note: yeah this is really god damn sticky. Bist, where on Earth (pun intended) did you acquire this? It's stupid sticky. At least there's drop instructions...
