Ok, I'm not trying to sound like a mean person or anything, but Leth, you said you've tried this synth 6 times, got 2 misses, 3 HQ's, and 2 karakul cloths. I'm pretty sure 2+3+2=7. Therefore, you've apparently had 7 synths.
This thing seems to have a very high HQ rate. I am 60 clothcraft, and trying to craft karakul cloth of 6 synths I have got 2 misses, 3 HQ2 (Silica) and only 2 karakul cloth.
