 Sometimes when an user reports: knobs 1 and 2 gets better performance, dev may get confuse whether he means the knobs 1 and 2 literally, or the 1st and 2nd knobs (knobs 0 and 1).

 Debug knobs are **zero-based**, which means:
-
 * The first knob is the knob(0) (or knob0 henceforth), and the last one is the 15 (knob15, likewise)
