Stuart,
As you know, the amount of molecules of oxygen in the loop cannot increase with depth as it becomes hypoxic. As in the Kiss system you block the depth compensating first stage in order to have a constant flow.
It is true that the volume of dilutant increases with depth, but if CO2 builds up just with the consumed oxygen then it is irrelevant the depth, CO2 in the loop should be the same and not increase with depth providing diver does not work more hard.
Please let me know where I am wrong.

I think the CO2 produced is the same regardless of depth, but the volume of gas in the loop is much greater at depth (more dil etc) so there is more gas flowing through the scrubber. Since the CO2 molecules have more gas to "hide" in, they get further through the scrubber before being scrubbed - hence the extended reaction front.
(Caveat: This is what I think but I am a newbie, so take what I say with a pinch of salt!)
