That's also fun up to some point. Whenever I optimized for fewest cycles in Codex it usually turned out to be "work with as many atoms per cycle as you possibly can", or something silly like building a solution on one side and mirroring the solution on the other side to get less cycles. The tedium of adding more and more tends to make least-cycle solutions less rewarding to craft, at least for me. (It's still fun though!)

If you open up a least-symbol solution for Codex you'll find a lot of interesting tricks used to reduce symbols. For example, grab-left-left-release-left-left can be accomplished with just grab-left-release-wait, if you sync it so the released atom is removed by another arm at exactly the right time. It's a nice feeling to successfully shave off even one more symbol using these hacks!
