1/2 star hq can be crafted from the shit )
3 star
Maths
Gold Ingot - Native Gold HQ adds 810 (2 star gathered material)
Wolfram Ingot - cobalt ore hq adds 527
Cashmere Cloth - Diluted Vitirol (2 star math) adds 1089
Final products
Saurian Gloves of Striking - Saurian Leather HQ adds 481, Rose Gold Nugget HQ adds 326. Haven't Terminus Putty HQ now but think that it will be +481 too.
So, hq all 2 star and less and try to hq 3 star maths. There is a lot of probability to get it even from nq.
4 star
Materials - hq doesn't exists for the most costed materials like kirimu leather and gives very few for others. Exclusions - platinum ingot, but it is not interesting if you can gather 3 star nodes. Not a problem to loose it or fail to nq. Probability of getting hq from nq with 12 ht rotation is >85%

Final products
Kirimu tricone - Kirimu Leather HQ +562, Saurian Leather HQ +460, Rose Gold Nugget HQ +281
kirimu Coat - oops! Kirimu Leather HQ +378 Rose Gold Nugget HQ +189
So, it's recipe dependent.
