My stake-in-the ground solve for 40G featured a waste stick sweeping out over 1000A, at 1/6T.  I finished that in about 30 minutes, and am almost willing to call it "trivial."

Wasteless 40G, though, was a challenging exploration.  What surprised me most, in the end, is how simple and elegant the "triangle" algorithm ended up being.  I don't know how competitive 70A will be, but this approach does feel like the Lubricating Solvents "Method(TM)" equivalent of 2023.
