Hi Fredrik_T,
bVOC(eq) = 0.5 ppm when sIAQ = 25 and bVOC(eq) = 15ppm when the sIAQ = 250 in case you have IAQ accuracy reaches to 3.
It's closely related, so sIAQ could be enough for IAQ.
Yes, you can say that your room is "relatively" dirtier than usual when sIAQ is high.
The reason might be complex like so many people or cooking whatever.
Thank you.
