Oceanic Dive Computer Pro Plus 2 ユーザーズマニュアル

This is especially important for repetitive dives when the
PDPS indicates adjusted dive times that are available for the
next dive, based on residual nitrogen or oxygen accumula-
tion (whichever is in control) following the last dive and
surface interval.

The PDPS provides a sequence of theoretical dive times
available for depths ranging from 30 feet (9 meters) to 190
feet (57 meters) in 10 foot (3 meter) increments.

During the sequence, no decompression times are only
displayed  for depths where there is at least 1 minute of
theoretical dive time available at the depth, taking into
account a descent and ascent rates of 60 feet (18 meters)
per minute.
