Residual Nitrogen Time
Residual nitrogen times are the black numbers in Table 3. This figure is based on the letter group you began the dive with and the depth you dove to.

To find your residual nitrogen time, you first locate the letter group you began the dive with on the right side of the table. Next, you follow that row to the column for the depth you dove to. The number in black is your residual nitrogen time.
