The above ratio profiles are what I would do. The 50% of deco at 6 then spit the remainder between the 21-9m stops. Rather than the new KISS idea of 5,5,5,5,5 I still prefer to extend the shalow section by nicking time off the 18-12m stops. Hesce my mucking arround with the times.
I am interested to see how you would manipulate these numbers to make it more agresive in an emergancy. I was wondering is there a formula or is it just a case of shaving.
No ruck desired. I wouldent use it unless i had to I am too unfit.

Hi
From looking at it, the runtime I worked out was 96 mins with RD and then checked on HLplanner and got 97 mins
, but I see it as 40 mins at 47, not 47 mins, as it took at least 5 mins for you to get to that depth, and I don't usually count that time. There are 2 spare minutes, so I guess another couple of mins at 6 polishes it all off at 100 mins.
The issue of having to cut short the deco is to cut the shallow stops rather than the deep stops, so I would stick to the deco as long as I possibly could, and then cut short the 6 mtr stop for example. To be perfectly honest, it really depends on the emergency and whether this emergency means I need to get out of the water, or whether I am able to go back down and continue the deco after sorting out whatever needed sorting out.
As an aside, doing 45 mins (40 mins BT at 48mtrs so 45 mins deco) on the 50% bottle is really maxing out the available gas, and this is where I would start thinking about taking along an AL40 of o2, which would take off another 10 mins and bring my time down to 90 mins.
So in answer to your question about being aggressive, you could forget the descent time and then do the deep stops, cutting short the 6 mtr stop if you have to. In terms of your runtime, I wouldn't be so bothered about doing more deco, although staring at Bob for an extra 20 mins might require a stiff drink when I get back on the boat.
