Huh, now that you mention it, the math doesn't seem to really add up lol. I assumed the "total" number was THC + all cannibinoids, maybe they're measuring others not listed. I'm assuming the rest of the composition (the final 16.8% beyond 83.2% total cannibinoids) is plant byproduct like waxes, maybe flavonoids.

But yeah, I'm generally staring at that terpene chart for my own purchase decisions!
