Why is it that some scents will throw VERY strong at 1oz per pound, while others are rather weak? I know some scents are naturally stronger than others, but even if it is a light scent you would think you would still be able to smell them. I use all oils from Peak except for two. I tested Mac Apple last night and was so excited, but it didn't seem to throw that well for me. I use J223 and 44z wicks. Anyone have an explanation for why this happens?
