I'm not sure whether we have the same understanding of accuracy vs. precision. I have explained the concept in an earlier post with an illustration (https://medium.com/read-or-die-hq/are-you-fit-enough-to-live-longer-you-dont-need-a-lab-for-the-answer-05e365b047d2) If you scroll halfway though you'll find it. In this sense I believe accuracy is the better choice. What do you think?
