I guess I would have to ask if the trichome-heads in the fried areas are still oily/sticky/gooey or not. I have seen light-baked plants where the trichome-heads seems to bake, they sort of crystallized and did not change after that.
 
When it comes to THC levels they will max out when a plant’s trichomes are mostly cloudy and some clear. THC levels will remain peaked until the trichome color has changed to mostly turning amber. Once that happens THC is oxidizing and your THC level is dropping and your CBN level is rising. In other words waiting will not get you more THC, it will get you less THC and more CBN ... if your trichomes are still pumping that is.
 
That is why I could never understand the whole amber trichome thing. You do it to get couch-lock but couch-lock comes from CBD and CBN makes you feel confused and messed up so to try to get more couch-lock people willingly throw away THC to get in return more CBN so they can feel confused and messed up and tell themselves it is as good as and the same as a CBD couch-lock stone.
 
If someone wants couch-lock purchase strains that are higher in CBD. Anything from 1.0% and higher is getting pretty couch-lockish and around 1.5% you are pretty glued so pick strains that are high in CBD but then harvest when the trichomes tell you that the THC levels are peaked instead of waiting for them to drop and then harvest like so many people do.
