If Tech 1 is shaving that sort of margin off of deco as standard someone is going to get them selves killed. Frankly I don’t believe it. This sort of profile is cutting edge and only for the super fit and super experienced. Posting it on a web site without background data is IMHO dangerous and irresponsible. Some idiot might try and copy it and end up in a wheel chair or worse. |
<font color='#000080'>Hi
Didn't give any guidance mate, only an opinion. Deco profile for single 50% deco was 55 mins not including the stops below 21 metres. EKPP profile is 21 minutes shorter but they used O2 at 6 meaning they could make that shorter, say by 11 mins which means a 10 minute difference. Depends I guess on your understanding of 'few'.
As deco is not an exact science I do not understand how you can say that they are cutting deco. We have talked previously about how the computers algorithms pad deco and do not treat helium correctly, or at least differently to how most recent research informs us. If you do not know the minimum or maximum with any accuracy because there are so many variables, then how can you say whether you are cutting or padding or just doing the correct deco? Its not just about time in the water, its about doing the deco in the right places and using the correct gasses and yes, some level of preconditioning.
I agree that one should not blindly follow someone elses deco profile. Anyone at that level of diving will have started with a baseline and with loads of experience will know what they can and cannot do over many dives.
