I checked my numbers after grinding out a stack of earrings to turn into a triple-leve. Hasty Touch + Steady Hand makes 70% success rate. After 7 successes I hit 100% quality with all normal conditions; I get 11 tries per craft. Essentially, I should HQ every craft if it runs by-the-numbers. Making just 6 lands me in high 80's/90's; 5 hits makes for about 40-50%. Of 40 crafts about one half were NQ. That's some awful luck.

Another WTF moment- during one of these sessions I got only 3 of 11 attempts, putting me about 6% HQ rate. Got the HQ. Makes up for the obscenity of a 27% success rate which is stated to be 70%.
