There is a sticky, actually. To me, it means testing the product by itself for self effects and effects on others. If it is a 12.5 mcg per spray, I use it in increments of 1 spray, usually with an intentional OD. I find the upper and lower limits (least that produces an effect and most effect I can stand). Sometimes, you don’t have a lot of product, so you have to do a mini version. With -eNone, I’ve only tested it to an upper limit once in public, and I’m not doing again. Same with TUTH. You don’t even really have to push 3-4 sprays. Too volatile. But with IO, yes, you should test 1 spray up to 6 in increments. People have a budget, so you aren’t expected to waste your items slavishly testing. You should, however, follow the guideline.
