To be fair, this time our 70 durab 4* recipes are slightly trickier in terms of progress. Previously, from 6.2 to 6.3, we just need very minor modifications, such as substituting Basic Syn with Careful Syn. This time, it's a bit harsher. Ideally, we actually wanna put in 1 more Groundwork during the Groundwork streak. But that will leave us with 1 fewer Prep Touch during WN II, which in the end causes a lot of problems since we'll run out of durab before reaching IQ10, which means we can't use Trained Finesse despite durab as low as 15. In the end, I decided to not add in that Groundwork, but invest more GP towards the end to patch up that missing progress.

In terms of quality gain, here's the test with my stats:
My rotation leaves me 2871 quality to be filled up with HQ mats. So I use 3 pieces of HQ mats. However, usually 1 or 2 touches will land on Goods, and that means even 2 pieces is probably sufficient (especially if doing it manually).
If 692 CP is too high for you, you can always simply remove a Trained Finesse (step 16 or 17), and that will reduce the CP requirement to 660 CP. Of course that will mean needing more HQ mats, but it's totally viable.
Once again, I strongly recommend using Trial Syn first to see if you can complete the item before doing the real thing. Also, pay attention to Specialist vs Non-specialist issue... your Non-specialists will have significantly fewer craftsmanship. So be careful.
As for the 35 durab items, well, we don't really need too many of these for the final product. But I think I made a very nice rotation below. The qual gain is also listed in the test above. Also, the Poor-proof Tricks of the Trade is not needed here, since we don't really care if 1 or 2 of these intermediate mats turned out NQ. But we do care about speed.
