Well as I said before I generally agree that one have to act along with the pheromones one uses but even if not doing so they will affect the targets anyway.If it was the contrary - pheromones would have been a scam, a placebo effect witch they are definately not.The problem in this situation is that when u act like don’t want to interact with people they understand it and whatever image you project in their minds they will not start talking to you for instance.
For example if an extremly hot and sex appealing girl is holding a gun and whispering to herself something like a madman, no guy is to be expected to close to her, right?But this doesn’t mean that guys will not percieve her as sexually attractive woman anymore.
The same is with the pheromones.U act them, u get real results, u don’t u just make a certaing image(depending on the pheromones u use) in other’s mind and no real contact.
Recently I had a verry interresting hit with HS freshman girls and Come Talk To Me Mix 2, (here is the thead Come talk to me 2 impressions)but in this occasion the pheromones made them willing to talk to me, to initiate a conversation without knowing me at all but it was my behaviour, that I responded with a smile, that I talked to them and asked if I can join their table that made the things going.So in that case the pheromones made 60% (not 50% because the girls influenced by the pheromones initiated the conversation with some simple chat) of the deal 
and I made the rest with just chatting and smiling.No big thoughts , no big game.Just being nice and having the pheromones do the rest.
So maybe there was some ioi even not shown because the contrary would mean that all the girs there didn’t posses a vno.
