You are still learning, that is all.
I found that experimenting helped me decide what worked best.
I would shave half my face one way and the other side differently, then evaluate over the course of my day narrowing down what works best. I tried a bunch of different soaps, blades, razors, preps, etc... and it comes down to trial and error.
And, I don't always get BBS (does anyone?). Maybe half the time I will get a really great shave, other times, I'll miss something and though I have a DFS I'll know it wasn't as good as it could have been. I think it is kind of like people who go to the casino, you hear from about it when they win, you don't hear about every loss. So, when you read about a BBS shave, take it with a grain of salt.
My suggestion, don't stress over it. You will get there.
I am frugal when I can be, so I am able to be extravagant when I want.
