I wouldn't sail this ship if I were you
1. The Q scale: from Q10 (Those who will always try to answer a question, regardless of whether they know anything about the subject involved) - to Q0 (Those who will never answer a question if they can avoid it, often pretending that they did not even hear it).
2. The D scale: from D10 (Those who can be relied on to do something that they say they will do, but not to not do something they say they won’t do), through D5 (Those who are equally reliable or unreliable on promises to do or not do things), to D0 (Those who cannot be relied on to do things they say they will do, but can be relied on to not do things they say they won’t do).
3. The B scale: from B10 (Those who, once they are reading a good book, cannot be dragged out of that book, even if there is a nuclear explosion or it starts raining money or something) to B0 (Those who will enjoy a good book but can be distracted from out of it by a fly going past, the opening of a flower in some far-distant field, or the surfacing of an idle notion).
4. The F scale: from F10 (Those who would always unhesitatingly step into a portal to a mysterious fantasy land with a compelling stranger if given the chance) through F5 (Those who would at least google the mysterious fantasy land first, ask if there were any catches, and tell someone where they were going) to F0 (Those who would never go).
