The right pipeline produces 4 simple products at a rate of 6 ticks, then makes a 5th just 4 ticks later by using the template silver atom.
The left pipeline makes triplex products at a rate of 4, then has time to make the 6th simple product.

Duping gold over silver is strictly worse (both ways require sacrificing two silver inputs, and gold production starts later), so I don't expect many gold solutions to beat this one.

Saved 250g from my first completion, so hopefully this is at least around the middle of the pack on secondary.

P.S. I had so much more fun on this than on catalyst, perhaps because the min was achievable and I was able to gradually shave secondary.
