I like the examples to illustrate both sides. I think if you had to always be positive in American you would say: A: "He always completed his tasks to our complete satisfaction" ("complete" being the superlative) B: "He always completed his tasks to our satisfaction" ("always" emphasizing the consistency of our satisfaction) C: "His work was satisfactory" F: <something that omits any mention his work> Although B sounds a little awkward to me.
