Sure, thanks, and don’t worry about them. 
As for the above mix, I wouldn’t spray 2-3 sprays of IS2X THEN top it off with another 2 sprays of IS.
If you want to develop a solid school sig, I would recommend finding your sweet spot with IG, then finding your sweet spot with IO and/or IH. Use that combination as your ‘foundation’.
Then, find your sweet spots for -none/Ammo, IS, and any other pheromones you might have/want/use. And layer accordingly onto your foundation.
So, for a basic, everyday mix, I might wear my IG, then either IO or IH (depending on my mood), and then IS on top of that.
If I wanted to take it a little further, I would experiment with a little p79, a little p74, a little -none..etc..
Remember that the most effective combos are balanced and have a specific direction. Don’t try and cover all your bases in one mix, or try and make a ‘super’ mix for every situation.
If you’re going to add something into your combo, have a good reason to. Don’t just toss it in for the sake of it, unless you’re testing it out. If you have a good solid mix, and you want to tweak it, by all means go for it, but understand that individual components can have a dramatic impact on the overall pheromone combination.
As for the A314+IG combo, I haven’t tried it much myself, so I don’t have much to offer. But I can say that, either on their own, is a solid foundation. Putting A314 into a mix though, is like tossing a full course meal into your salad bowl. It might work, but it might be more ‘meat’ than you needed, when you could have used more ‘seasonings’ (IS, p74, p83, p93, TAK, TAF, etc..)
