Indeed, some or all of the figures have been wholly fabricated.
One of the reasons why Hang Kra Rok(ST1) is your favourite, is it's equal parts of THC/CBD, at approx. 7% of each.
Tanaosri(WA1) is probably closer to 9% to 10%.
They do themselves no favours making up the figures, as many people prefer something balanced, as opposed to strong to the nth degree. Hence your preference for ST1.
