This really doesn't seem to be the case if you're failing PbP because you didn't use SHII. A wasted step on something that costs CP is a huge loss compared to using SHII steps for PbP, esp since you;re using comfort zone and you want to prolong your craft as long as possible to benefit from it.
Four stars is actually easier than the 3 star recipe books. If anything, it's more or less similiar to 3 star crafting. I mean even I'll admit that HQing for the recipe book is RNG, thats why you try to fish for it and cut your losses if you forecast a fail with reclaim.
Read above with 4 stars being closer to 3 stars as far as difficulty/RNG is concerned. HQing materials like kirimu leather is a feat of its own...that's why you have other items that can be HQ'd when it comes to crafting those equipment (such as kirimu coat) And honestly, a kirimu leather is pretty low-profile crafting compared to an offhand or a piece of equipment that you can mass produce these to increase HQ yields anyway. If a crafter is going to quit because they got 2 NQ on materials whose starting quality cannot be boosted, then I'm sorry, but you really wouldn't have the nerves to get into high-end crafts, espesically if it was to provide for the FC or to make a business out of it.
What kind of crafter gets themselves into this scenario? At that point you would've been better off cutting your losses with a reclaim if it was really that bad. I mean there's bad RNG, and there's butting your head straight into a failed craft.
From what I see, you're using basic touches whenever you can. The problem is like you mentioned, you're expending so much CP.
If you're trying to HQ from it, you'll benefit hugely from prolonging your craft as long as you can to increase the number of good conditions and to benefit from comfort zone. When I do my crafts, I always use hasty touch with SHII. This allows me to have enough CP over to prolong my step for a second comfort zone, one MMII, and a second MMII if I get 4 TotTs. This is over the course of 20+ steps, instead of being sub-15 steps because you run yourself out of CP.
