He can't guarantee that because it doesn't. 392 Craftsmanship gives me 115/114 progress with Ingenuity 2 active. How much would 359, his recommended amount? I also know from experience that it won't work. Without Artisan you can not finish two star 40s in one step. Thankfully this 100% 40 durability rotation works. Make your Twinthread, Rose Gold Nugget, etc, with the rotation. It works without Artisan Tool. The use the same rotation but slightly modified for the items you're after. Specifically follow this part:

Solution for non-Artisan 2 Star

Simple solution. Use the rotation to make the two HQ base (Twinthread, etc) for your two star synth. Drop the first basic touch from the rotation and use Careful Synthesis II instead. This will reach 100% without any RNG (just!) but it will require the two HQ materials. That's not a problem with this rotation now though!
So use the rotation to make the HQ ingredients for the two star. The rotation above HQs without Artisan if the two ingredients are two star and you follow the above modification.
