I'm not sure I can answer that question for you. I think your nitrox instructor told you to keep your PP O2 to around 1.4 (for spearfishing), you would want to keep your BT short and do a deep stop. It would be better to not exceed the no-deco limits and I think you need to have some redundancy (like a pony bottle). Most anyone who is qualified to give you advice on this (and I am not) would encourage longer surface intervals.

In any case, I suggest a very gradual progression into more aggressive diving, and make sure you have oxygen on the boat.
