The OP is not a high 3 or 4 tho is she? It's not meant to be anything but ugly, it's meant to be more accurate than seeing hair coated in silicones and meant to 'level the playing field', not have one person use a light application of a light product and another use a heavy application of a heavy product.
Conditioner can weigh down or pull out looser waves particularly, as can brushes, towel turbans, finger combing, silicones .... Most commercial leave ins are packed with silicones and I have no idea how you would apply it without either smoothing or scrunching both of which are interfering with the curl pattern!
I have waves/ curls between 2a and 2c with conditioner scrunched in but without any styling products or diffusing. My hair looks much like the OP's today because I brushed it when wet so I can dye it tomorrow. I lost a massive amount of curl a few weeks ago despite doing most CG things because I accidentally used a silicone in a reformulated conditioner.
Even in frizz/ pouf you can see a curl pattern if any head of hair is left to it's own devices, you just don't get definition or clumping. Of course the best idea will come with a few weeks of CG, generally if you can see a 2a with dry typing you will get, say, a 2b with a few weeks of curl love so you will often see people state that in a typing thread.
