My hunch was that making this quicksilver-iron-gold intermediary product should be pretty feasible at 3/2P (5 cycle tape loop and spending 10 cycles to make 3 product), and converting it into the final output would be very simple. i'm sure there's more minor optimizations here i missed but i'm happy enough with just reaching sub-100. i would assume that's pretty good on this, what with the  5-to-3 input to output ratio complicating things, but with how full of wizards this community is i wouldnt be surprised to find out that podium's sub-50 or whatever

i experimented with a qs-i-qs-s intermediary instead but didnt seem like it would go under 100. idk maybe there's more solution space in that direction
