No, I don't have difficulty with measuring, weighing, percentages, etc...but yes, I did assume that the 1 oz trial sizes were actually 1 weighed ounce. CBA and GB464 can take more fo w/o the complications that I'm seeing with the C3, and I'm finding as I go along that no two waxes are the same by any means...trial and error. Appreciate the feedback-I'm determined to find my way with the C3
