Hi Dan,
Nice to see you got your products and that you have started a journal. There are some sticky posts related to application points. Here is the link.
Regarding dosage, it’s mostly trial and error until you find your sweet spot. Start with a single spray and work your way up if need be.
Regarding diffusion, let the mones do the work 
. Just apply when on a spot not covered by clothes. And be advised that products tend to burn up faster when the weather is hot or while doing intense physical activity.
