Now, it's not hard to confuse me, but the Padi OW manual has managed it even more easily than normal. I managed to suss out that I needed stylish, colourful kit, according to the manual (black just doesn't cut it apparently!), but theres a question in Section 5 (section review question 6), that has me a little confused.
I've been fine using the RDP so far, but this one seems a little different to previous questions.....
What is the minimum surface interval required between a dive to 20 metres for 29 minutes, followed by a dive to 14 metres for 39 minutes?
So...here's my working...
1) Using the RDP table 1, my pressure group after dive 1 is M
2) Using the RDP table 3, I need to be in pressure group P before I can do dive 2.
3) Therefore, this suggests that I would have an interval time of zero if I wanted, as I do not have to wait for the pressure group to lower from M to P. If I'm right, I assume this is a theoretical time only, and some form of minimum time should apply?
Is this right, or am I doing something wrong here?
Thanks
Rob
