I apply my SOTD a little higher up on the underside of my arm because I hate getting it on my watch band. After a few days of different scents mixing together and sticking to the band, there is a funky odor that is just rank hanging around my watch like a cloud. So, I spray higher than my watch band will slide.
I do think pulse points make sense, especially in cool or cold weather. Maybe not so much in hot weather.
