Paraphrasing the tester site:
Standard: Equal focus on Quality and Progress
Rapid: Focus on Progress -- Higher Fail Rate
Bold: Focus on Quality -- Higher durability loss
Wait: Observe. Perhaps increase chance of success??
What I've been doing with moderate success Standard for general production -- if your durability gets low, start hitting Rapid and hope for it to turn around!
The animation played when you use an ability means something as well, the bigger the effect the better you have done -- not sure how to use this to pick what to do next.
