The last stuff I've crafted were 2 star items and I just want to start with 4 star stuff (with literally 0 experience).

Thats the rotation I came up with after playing around a bit:

Comfort Zone
Inner Quiet
Steady Hand
(Tricks of the Trade)
Piece by Piece
Piece by Piece
(Tricks of the Trade)
Piece by Piece
Careful Synthesis II
Careful Synthesis II

There are plenty of possibilities for TotT during the first steps and I just calculated with 2 of them.

Manipulation
Comfort Zone
Waste Not
Steady Hand II
Hasty Touch
Hasty Touch
Hasty Touch
Hasty Touch
Hasty Touch
Manipulation
Steady Hand II
Hasty Touch/Basic Touch
Hasty Touch/Basic Touch
Hasty Touch/Basic Touch
Hasty Touch/Basik Touch

Depending on my overall TotT triggers I use Hasty or Basic Touch

Steady Hand
Great Strides
Innovation
Byregot's Blessing
Careful Synthesis II

398 CP
452 Craft
412 Control

I was able to 100% HQ 2 of 4 Caviar with 663/5783 start qualitiy, the others had 40 and 80% success.

Are there some things which I could improve in this rotation?
