Analysis

Arm 1's unique timing first offsets the berlo wheel before regrabbing, and then lets arm 3 delay its own regrab by a loop. This constructs the output stick while offsetting the berlo wheel a second time, allowing for proper duplication. The bi arms also build two sticks at once, accessing both "halves" of the berlo wheel. Also worth noting is the cool simul-pivot.


Tissue Bet

If biggie has bested me yet again, he will have earned it. For all three arms, the timing is delicate and the geometry is tight. Without any outside knowledge, this feels hard to beat.
