My computer does not start counting down the SS until shallower than 6 m; at 18 ft. And it would like me to stay between 10 ft and 18 ft (or is it 12?).

I don't know if that is the case, since when underwater, pressure is applied to our whole body, if it was only applied to our lungs, then a diver who empties his lung completely at dept and perform an extremely rapid ascend would not suffer DCS because there is maximum gradient of nitrogen between the lung and body. They would then simply inhale 100% oxygen on the surface.
The fact is that the body will off-gas with or without pressure differential in the lungs, but from pressure on the body. After that, the transfer of that off-gassed nitrogen to the lungs will depend on the the percentage of nitrogen that is also being inhaled since nitrogen is being transferred to the bloodstream and exhaled at the same time, so the less inhalation of it, the better.

Seeing as this is advanced diving we should try to be somewhat accurate in our language while at the same time not getting mired in theoretical what if's. Otherwise the whole discussion is akin to building a house on sand or arguing the difference between brass snapbolts or stainless steel.
First, as Rob addressed, are we talking about decompression stops or safety stops. There is a difference and the approach to either is not the same.
Second, the OP needs to re look at his adjusted depths. I'm pretty sure 3m is not 2m on a standard EAN mix like 32%. Assuming a 50% adjusted depth will of course make one think there is a tangible difference in offgassing). Upon reflection, the real adjusted depth will be more along the lines of variance of a couple of feet which most recreational divers experience when doing a safety stop no matter what the mix. Compound this with the fact that a safety stop is only 3-5 minutes in length and the difference is neglible.
Just trying to keep it real.
