Feels like I am missing something

You forgot to add the extra +10% HQ chance of Unearth 1 (which you can use with 700 GP) in the comparison.
Either way, I'm too lazy to do the math myself, but I ve been consistently getting 3 HQs, or 4 when i get a little lucky, per node, so im pretty happy with it!

I also like to know that at least 2 items will be guaranteed HQ, even if RNG screws me over. But in pratical terms, both rotations are pretty solid. When I feel like gambling, I don't even use field mastery II and use that 100 GP somewhere else, lol.
