Here is a quick update on the status on the bigger cook, I still need to wash the resulting oil. Anyway:
38g of CBD isolate was dissolved into 700ml of %95 ethanol, Everclear brand grain alcohol.
%37 HCl solution was added until ~2 pH was reached on the color chart while the solution was slowly heated to ~70c in an oil bath.
Temperature of oil and reaction liquid were monitored with a thermometer. A piece of plastic was placed over the top of the jar to reduce ethanol evaporation.
The mixture was swirled back and forth periodically for a moment throughout the entire reaction of about 5 hours.
The mixture darkens quite a bit after a few hours, and even more so still to about 5 hours at 70c.
After 5 hours, the color of the reaction liquid has darkened significantly, the reaction was left to cool to room temperature and brine was added about 2 parts brine to 1 part reaction mixture and mixed.
After a moment of mixing the brine into the reaction liquid, the oil pushed out and accumulated at the top of the reaction liquid. It was collected with a syringe for further processing.
~55ml crude THC oil was collected. I will continue to update this experiment. I must still wash the collected crude THC oil, heat to 150c and deacidify/wash again.

Additional advice. Before heating, you must measure pH. If it is acidic, you will harm.
I didn't see this until just now. Had already brought it to 150c for a moment in the oven. Last I checked pH was before I pulled it off the heat at the end of 5 hours, so unfortunately, I will have to do better next time. This stuff is extremely tough to work with, it cooled into a puck in the bottom of my beaker. It got a bit lighter in color and more translucent, extremely stringy trying to seperate a dab to smoke, it takes away the craving but I'm not terribly satisfied. I've been trying to eat a good bit to catch a buzz but I don't notice much there either.

Perhaps the conversion went further into less active substances. If some of the acid was in the remainder of the mixture. I think it is necessary to correct this moment for this synthesis or not to use additional heating without vacuum at low temperature. Your first successful experience without additional heating speaks of the same thing.
