e.g. saw tooth pattern (data pattern) mapped to poor buoyancy control
rating the dive based on the dive features
e.g. long bottom times receive low rating
Risky dive with some minor problems. Because your bottom time of 12.0min exceeds no-stop limit by 4.0min this dive is risky. But you performed the ascent well. Your buoyancy control in the bottom zone was poor as indicated by ‘saw tooth’ patterns marked ‘A’ on the depth-time profile.
