its a toss up really.. you'll get extra cp from comfort zone but unless you can use touch with the cp it wont help.. plus with that amount of cp you should already have enough to 100% hq your synth. ingenuity 2 could give you extra quality as well as progress, if you have enough craftsmanship it may even reduce it down to 1 progress step to finish or 2 steps for 2* 40 dura.

for 1* 40 dura I use..

CZ,IQ,SH2,HT,HT,MPN,HT,SH2,HT,HT,MPN,HT,HT,SH2,IG2,HT,GS,BB,CS2

going from zero quality it gets pretty high if not just flat out 100%, if using 1 hq mat its about as close to being 100% all the time as you can get whilst relying on hasty touch. with all hq mats its virtually guaranteed all the time. (but its still not a 100% guaranteed rotation)

this rotation starts with 345cp and no food. actually if I remember rightly there's 2cp left over so could be done with 343, but check that first.

you'll have to adjust for your craftsmanship lvl as I'm not certain of the min for it to work.

this would work on 2* as well but you'll have to work out how many hasty's to drop to get your progress to 100%.
