I added the two top bottles 12mg and 6mg and got 9mg
then I added the bottom.....3mg and 0mg and got 1.5 mg
Low is 1.5 and high 9.....I start at 1.5 and add 1.5 till I get to 9...then the middle is the MG
So.....1.5....3.....4.5....6....7.5....9.....the mg is half way between 4.5 and 6...5.25mg or maybe not
