This does not deny that some form of superchlorination may be occurring in the cell, but it also shows that water not having gone through the cell recently is still at risk.

I would guess as much though with sufficiently high levels of chlorine (independent of whether there was an SWG) the CC should get reduced between a somewhat slow breakpoint and a somewhat faster exposure to sunlight. At least that's the current thinking (subject to change, of course). Ironically, the typically higher CYA levels and somewhat lower chlorine levels found in most SWG pools means that achieving breakpoint takes even longer outside of the salt cell (that is, it takes longer to get breakpoint from the chlorine in the pool because the HOCl levels are relatively low). Fortunately, the salt cell itself has high chlorine levels so eventually after many turnovers most of the water has gone through areas of high chlorination to achieve breakpoint. Again, my speculative theory.

First, my aquarite turbo cell has what looks like plastic mesh around the plates. This should spit out lots of vortices to both slow the water down and mix it a lot near the plates, suddenly that makes sense. High turbulence should move the chlorine away from the plates more quickly. Clever mechanical tricks are always a good thing.

Yup, creating all sorts of vortices and somewhat turbulent flow (what I would call "controlled" turbulence since normal uncontrolled turbulence causes all sorts of problems) helps sweep away the generated chlorine away from the plates. Sounds like a good design in your system.

Second, someone with a two speed pump should be able to test whether slower flow is more or less efficient somehow. This would not be an easy test since fairly accurate estimates of flow rate would be needed, but worth considering.

I would suspect that the SWG manufacturers designed their systems for typical flow rates and that slowing down the flow would result in lower efficiency. Anyway, I think we've all pretty much concluded that SWG systems have a lot going for them regardless of the specifics of the (electro)chemistry that is involved.
