Feels like I am missing something

What do you think about this one?

Toil (300gp) > Unearth II (300gp) > Sharp Vision (100gp) > Gather x5 (at 37% chance) > Gather x1 (last hit HQ)

Figure this gives you x5 swings at 37% HQ chance and the last swing guarenteed HQ. The only downside i can see is that the sharp vision likely won't get you to 100% (probably 91-95%).

The 100GP Sharp Vision is SVII, and add 15% for me that's 100%.
As to whether to use Unearth II (UE2, 300GP) (+30% HQ) or Bountiful Yield (BY, 200GP). UE2 will give, average, 1.5 more HQ per node-spawn. BY will give you 1 more, every time, and costs less GP -- which is important even if you have 700GP for the UE2 rotation, because it takes an extra 20 Eorzaean minutes to recover the extra 100GP for UE2. But if you have the time and the GP, UE2 is better, on average, by 0.5 HQ per node-spawn.

Different people can rationally choose either option, depending on their situation and tolerance for risk.

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.

I'm planning on use toil again soon on legendary nodes once I hit 700 GP.

This is the rotation imma use -》Toil / Sharp Vision II (100% with 725 gathering) / unearth (+10% HQ) / collect 5 / Deep Vigor + Bountiful Yield

This is a guarateed, 100% RNG free, 2 hq items at least per legendary node (with 5 attempts with at least 18%)

Just hit 700 with HQ Dzeamel Gratin /grin

My rotation for gathering fron the legendaries: Swing to uncover, SVII, KYII - BYII, Unearth - Leaf turn.

This gives me 5 swings at 100% and 20% to HQ with 3 items a swing and excelent chances that one swing will yeild 3 HQs.

It occurs to me that 700 GP may, under some circumstances, provide a bigger yield.

Consider the Volcanic Rock Salt. You get 5 per swing naturally. King's Yield bumps that to 6 at a cost of 400 GP. KY2 bumps that to 7 at a cost of 500 GP.

By the time you have 700 GP you are 100/15 for gathering/HQ, so you do not need to worry about increasing your gathering chances.

Toil (or a swing to reveal and then Solid Reason) costs 300 GP and let's you take 6 gathering swings at the node. 6x6 is 36, whereas the old standby is 5x7, or 35. So with 700 GP you can increase your take from nodes that naturally provide 5.

Sadly, this does not work out for nodes that naturally provide 3. 5x5 is 25, but 6x4 is only 24. Still, if you are aiming at 700 GP, and you do need to hit up that (or those? Can only think of just this one) ARR node that provides a base of 5 items per swing, you can get more for your troubles this way.
