dumpsterDiver:
I would not recommend what you are doing. Doing a dive to 185 on air for 15min,and using decoplanner to plan tables,your deco obligation without oxygen is 36 minutes and with oxygen 23 minutes. You have a very small pony for air and oxygen (5-8 minutes) which tells me you don't have adequate gas to complete deco if you should have a primary gas failure,plus inadequate amount of redundant deco gas. I would conclude that if you are using a pony bottle that you don't have a H or Y valve to shut a regulator down during a freeflow to prevent sudden gas loss,hence inadequate redundancy. I'm not going to hammer you,just point out that I'd recommend re-examining your dive profiles. I know somebody that had to blow a lot of deco due to inadequate redundancy,and he spent many hours in a chamber and a month using a diaper due to bowel and bladder incontinence from CNS injury. Just remember a deco dive is like being in the overhead,you can't ascend directly,you have to be prepared to address all your problems.
