">85% of answers are helpful & accurate"

People can usually tell if an answer isn't helpful, but not always that it isn't accurate. Depending on the context, 85% accurate might not be good enough.

95% of answers could be accurate. Combined with the 85% that are helpful and you have “85% of answers are helpful & accurate.”

Who would intentionally downplay their accuracy in marketing materials by conflating the statistic with another?

Instead of using the lower bound, wouldn't it make more sense to say "85% of the 95% accurate answers are helpful"? Or perhaps "95% of the 85% helpful answers are accurate"?

In both cases, the number for "answers that are both helpful and accurate" is lower than 85%.

Yep, the other commenter is right--85% is helpful AND accurate. I'd love for you to give it a try and see if 85% is not good enough though. There's always more to push on quality and the more real feedback we get the better we can prioritize what people need.
