Guys,
On my last dive trip I got a bit confused about how to determine bottom time.
The way I learned was to use the Total Dive Time as Bottom Time when completing my logs. However, on my last dive trip I did a couple of specialties and my instructor there (different from when I got my OW and AOW), told me that my bottom time is the time I spend at the deepest point.
I would have expected the first method (Dive Time=Bottom Time) to be the correct way as it is more conservative (and thus also the reason why people use computers as there is a significant difference between tables that require the bottom time calculations, and computers that use algorythms that don't punish you for decent and ascent profiles).
Please note that I dove with a dive computer and was always aware of my limits. However, I do want to remove any confusion about bottom time calculations as in the end we all need to be able to use the RDP tables without computers.
Thanks.
