NQ 7466

HQ1 1920

HQ2 447

HQ3 167

The BGwiki description of how crafting works implies there are 3 independent probabilities:

1) Break or Success

I could potentially reanalyze some of my data for break rates if people particularly care, but at the moment I am ignoring the first comparison because that's not supposed to be related to what Rusks do.

2) NQ or HQ (varies based on HQ Tier, would be 1/4 for this synth)

Rusk:

26.14% (2614/10000)

No Rusk:

25.34% (2534/10000)

Chi squared p=0.196

The raw HQ rate is not significantly different between these samples.

3) HQ1 (12/16), HQ2 (3/16), or HQ3 (1/16)

Chi squared p=0.180

The HQ distributions are not significantly different between Rusk and No Rusk either. If I include NQs in the stats and assume steps 2 and 3 are not independent, the difference in the distributions becomes (p=0.164).
