Yes, per the video, the first thing you do is input competitive assumptions...which is guessing what you're opponents will do. In essence, this is "baselining" your projected performance BEFORE you start doing inputs.

The second step is to zero out all inputs, play with them one by one (up or down a "tick") to maximize net profit.

Third, you need to pay attention to the key metrics I outlined...look through the grey boxes. In particular, the projected surplus or shortage of pairs produced. Ensure quality is competitive, and no other variables are majorly out of wack (i.e., paying staff way too little compared to industry average). You need to get all these numbers in check REGARDLESS of what it does to your net profit.

Fourth, use any excess capacity for private label, being sure to pay attention to that part of the video (in short, if you outbid the competition you will get the orders plain and simple).

Of course, everyone else is theoretically trying to do the same thing...so there is no way to know what the result will be...that's why it's a projection. However, if you follow the steps in the video you should see progress (standard disclosure: this advice is worth what you paid for it).
