RNT Table Asterisks - 1 The repetitive groups represent the amount of nitrogen in the 120 min half-time tissue If at the end of a surface interval you have a repetitive group that leads you to a double asterisk in the RNT tables (**), it means that the tissue N2 tension in the 120 min tissue is still higher than the inspired N2 tension at this depth Therefore, during the dive the 120 min tissue will actually off-gas rather than on-gas resulting in a lower group letter
RNT Table Asterisks - 2 To avoid publishing separate off-gassing tables for 10 and 20 fsw dives, the <strong>USN</strong> decided to have their divers assume that the repetitive group does not change during the dive (i.e. it is the same after surfacing as it was when the diver began the descent) This is in contrast to normal repetitive dives in which the repetitive group is always greater after surfacing than it was at the beginning of the dive
