* Dives following surface intervals longer than this are not repetitive dives. Use actual bottom times in the Tables 15-14 and 15-16 to compute decompression for such dives.

Previous Dive ______________ minutes ______________ feet ___ ___________ repetitive group designator from Table 15-14 if the dive was a no-decompression dive, or Table 15-16 if the dive was a decompression dive. Part 2. Surface Interval: Enter the top section of Table 15-15 at the row for the repetitive group designator from Part 1 and move horizontally to the column in which the actual or planned surface interval time lies. Read the final repetitive group designator from the bottom of this column. _________ hours ______ minutes on the surface _________ final repetitive group from Table 15-15 Part 3. Equivalent Single Dive Time for the Repetitive Dive: Enter the bottom section of Table 15-15 at the row for the maximum depth of the planned repetitive dive. Move horizontally to the column of the final repetitive group designator from Part 2 to find the Residual Nitrogen Time (RNT). Add this RNT to the planned bottom time for the repetitive dive to obtain the equivalent single dive time. _____ minutes: RNT +_____ minutes: planned bottom time =_____ minutes: equivalent single dive time Part 4. Decompression Schedule for the Repetitive Dive: Locate the row for the depth of the planned repetitive dive in Table 15-14 . Move horizontally to the column with bottom time equal to or just greater than the equivalent single dive time and read the surfacing repetitive group for the repetitive dive from the top of the column. If the equivalent single dive time exceeds the no-decompression limit, locate the row for the depth and equivalent single dive time in Table 15-16. Read the required decompression stops and surfacing repetitive group from the columns to the right along this row. _____ minutes: equivalent single dive time from Part 3 _____ feet: depth of the repetitive dive. _____ Schedule (depth/bottom time) from Table 15-14 or Table 15-16 . Ensure RNT Exception Rule does not apply. Verify allowable repet from Table 15-1 .
