I found a nice mix of the rotation I used to use for those impossible Master II Books from ARR which seems to be working out for me for the most part. On my most recent Two-Star craft I had around 60 total steps taken, with less starting CP than some of the others here however possibly higher from procs.

I am by no means an expert crafter since I divide my time among many things, but this is kinda what I've come up with and have generally had success in - I'm still trying to find a good use for the specialist skill: Trained Hand. It's incredibly hard to put down a system like this since in my experience no two Synths are the same...

Key Point: Only use Precise touch if Steady Hand is active.  

Food: I generally use HQ Seafood Stew for these extreme Synths, which is fairly cheap to make yourself.

• Makers Mark (Adds 13 or 14 Stacks)
• Comfort Zone
• Whistle While you Work.
• Inner Quiet
• Flawless Synthesis (Until Makers Mark Depleted)
  • Use Tricks of the Trade when available
  • If you get two "Good" statuses, Satisfaction will be available - use it
  • Refresh Comfort Zone once it's off
• Ingenuity II
  • ToT / Satisfaction.
• Steady Hand II
  • Satisfaction / Precise Touch

• Rapid Synthesis X 3 (This is the Major RNG Part, but failures are not the end of the world. Also how many of these you need is based on your craftsmanship.

  • Satisfaction / Precise Touch

  You may need to refresh Ingen II & Steady Hand II if things go bad (or tons of procs), but it's statistically unlikely. Just keep tabs on the remaining progress.

• If CSII will increase progress too much with Ingenuity, use Hasty Touch until 10/70, or until Steady Hand is gone, at which point you can use one or two CSII

• Masters Mend II

After this point, the entire process is a play on procs.

• Use Satisfaction when Available.
• Refresh Comfort Zone
• Nymeia's Wheel when nearing 20/70 and you need some extra steps.
• You should have enough for a second Masters Mend II, and yet another Masters Mend I if the proc gods are with you.

Sorry if this isn't much use - it's assuming you have taken Specialist in whichever class you are using as a means of gaining a few extra CP. I didn't meld nearly as much +CP into my gear as others, but I made it work.
