That would be symmetrical. It would gas on less and off to match. It would be just another compartment.
Silly question: Are you a hard man who "doesn't get cold" and dives in a thin suit because that sounds like a classic cold induced skin bend. The gas gets in while you are nice and warm with big blood flow and when the cold shuts the blood vessels down it can't get out. You are, effectively, changing the time constant of the compartment mid dive.
It is always in well cooled surface tissues.
That's 75mg and they are a quid a hundred so why not try it?
A few items:
1. I too suffered this problem for years, but traced it. It is due to profile. I have permanent marks on the skin of one shoulder as a result. It does not affect just your skin: one finds out the real damage years later.
2. It is not symmetrical: on-gassing is a rising expontial, off-gassing is a falling exponential. This means tissues take much more time to off-gas than on-gas.
3. You raise a good point: Cold is a problem. Not good to get cold as it does change gas flow, particularly on shoulders and neck. I do not notice the cold, but the gas in my tissues do.
