So,
I just HQed 5 LTW items for the Master 2 book from 0 -> 100% without any problems. Most of the time i had 40-50 CP left and 30-40 durability. Finishing with a Byregot on 11 Stacks with only CP+ melded lvl 60 HQ gear gave me 4.550 quality, thats more then 50% of what is needed. I only used Hasty Touch twice, and to finish it the item it was enough to Rapid Synth + carefuly Synth II x2
My base stats: 641 Craft 608 Control 397 CP - no food or specialist actions used.
You might want to consider leveling every other craft to 50 first. I Had no need for ingenuity/Piece by Piece/Manipulation or what so ever to do this tho.
Just stop being stuck in 2.0 mode and the "HASTY TOUCH TO GAIN STACKS OMFG BBQ!" System. Get your ass to 11 stacks as quick and safely as possible. i.e. use Precise Touch when you got Steady Hand II up asap - the more stacks you get early on the more quality you get on each other touch you land and finish it off with Byregots Blessing. And if you're on a specialized job use Byregot's Miracle (on 6+ Inner Quiet) if you got Steady Hand II up and a Excellent shows.
Crafting a 60 one star is way harder then those old items
