Hi everyone! Four star crafting as many folks have pointed out on the forums is very similar to three star crafting. Rotations using Makers mark and Piece by Piece are stronger overall while rotations using Muscle memory and Ingenuity are weaker but save time. In general what this means is that versions of Rath's MaMa PbP rotation are best for hands on crafting. While variations of my MaMa Careful Synth rotation are best for macro work. Below I will outline both rotations and how I current recommend they be executed for Four star crafting.

Option 1 Best for Hands On Work - Modified version of Rath's MaMa PbP:
Using Rath's modified rotation you must succeed 12 out of 16 Flawless Synthesis. Three are under SH, so statistically you are only attempting to succeed 9 out of 13 flawless. This means you can almost always safely ToT once, and often safely ToT twice. Likewise if you have MAX CP and use SHI (NOT II) you can squeeze out TWO extra 18 point options (precise/basic/innovate). Note if you ToT twice you can use SHII at the end (if executing the MAX CP design). I've listed two versions one for Low CP and one for Max CP. Note that if you have slightly less CP than the low version you can change some of your SHII to SHI.
MaMa PbP (4 Star Low CP) - Required stats 1023 Craftsman and 437 CP (Character base stats 995 Craftsman, 389 CP and HQ Baked Onion Soup):
MaMa PbP (4 Star Max CP) - Required stats 1023 Craftsman and 473 CP (Character base stats 995 Craftsman, 425 CP and HQ Baked Onion Soup):
Please Note: The pictures show less flawless synths than you actually get. MAKE sure to use up all your flawless synths. Also while executing either rotation after your flawless synth cycle, make SURE to check your progress and don't accidentally early complete your good OR fall short from completion! Also note you can use other food for these BUT you may need additional base crafting to miss the same flawless synths!
