How many clusters per gather?

[User_Name]

You get clusters and grade 4 carbonized from lvl 50 undisturbed tree nodes in mor dhona using truth of the forests. I'm not sure where you get them with miner.
You get 6 attempts
You can use an ability to immediately clear all the weeds or w/e so you get 6 full attempts
or spend 2 attempts clearing weeds at the expected spot, and 4 attempts gathering (and if you use abilities you can double/triple the clusters you get)

The node only pops once per eorzea day (always at the same time)

Note: normal nodes are 4 attempts. Undisturbed (truth of forests/mountains) nodes are 6 attempts, but require removing clutter before you can gather, which takes 2 attempts or 1 high-gp ability

Is it always 2 attempts to clear it manually? Or can it be more because there's a percent chance you won't clear it?
