I'm just brand new to ICmag forum, and I would just like to give you this link to a test grow with a 6h40 ON/12h OFF flowering test:

But I wanna say that:
-Cannabis is a C4 plant so there is no point in saying that it cannot exploit a full 12h light cycle.
-A study by J.R. VALLE show that diminushing light to 10h of light instead of 12h , will also diminish the THC content by more than a half. So, you can expect an even more important diminution with a 6h40light cycle of the cannabiboids content
Here is a link to an abstract of the study:

But nevertheless, it can be an interesting cycle if you wanna speed up your flowering
Cheers

IMO, without a side-by-side experiment, with exactly the same conditions (light wattage, surface, cuttings, etc ... ) made at the same period and an analyze of the cannabinoids contents, you can not judge of the effect of your light manipulationThat's my thread over at AN that you provided a link too and I can tell you this there was NO diminishing in THC I spread some it a round the comunity and was told that it was some of the best pot they ever smoked.
I'm not really convinced by this argument because away from the effect on the oxydation/reduction of phytochroms and thus the flowering activation I don't see how a dark period over 12hours will affect cannabinoids contents.I just think they are looking at if wrong and should be labled Dark periods over 12 hour deminishes THC. Again they were working on a 24 hour day.
