Look, I don't think it's possible to go below 100g without tracks. You need either a piston and an arm or three arms, and while a piston's just easier given the molecule shape (so I says, says I.), I gave it another shot with three arms instead and...*mwah*. Down from 789 cycles when more arms do more work.
I suppose I couldn't be too surprised if someone comes up with a way to push G down to double digits. I already considered myself 20 below par (two pistons) when I made my first version. There's not a way to get full access on the things that need full access with any less than this, though, and I don't yet care to learn Syrup Tech.
This might be the first week I felt actually, truly competitive. Maybe you can do better by getting the bonder accessible fully by 2 and half-access 3, but I don't feel equipped to juggle that at present moment.
