Er, sorry. That's my fault. The ~1/12 refers to the AF piece that drops. Not the actual droprate. I was trying to get at how that number could increase while claiming to keep the droprate the same.
Assume x is the droprate.
f(x) is the droprate for the second slot, wherein f(x) is the adjustment to make the ToAU is equal to the droprate for the first slot (assuming that it's equal).
However, this debunks the idea of simply adding a second slot to double the AF in icelands, which is good to know. Which is where my wires were getting crossed. If the icelands AF is doubled, it's directly to whatever the droprate, x, is.
I'm glad everyone helped me through that.
