Accidentals often possess three or more deltas. In tracing them only the extreme deltas are considered, the tracing beginning at the extreme left delta and proceeding toward the extreme right delta, as illustrated in figure 293.
[Fig. 293]
In a double loop or accidental the problem of where to stop tracing is sometimes presented. The rule is, when the tracing passes inside of the right delta, stop at the nearest point to the right delta on the upward trend, as in figure 294. If no upward trend is present, continue tracing until a point opposite the right delta, or the delta itself, is reached (figs. 295 and 296).
