With the exception of the brine, it seems like most of the recipe items (glaze, rub, etc.) make far more of the component than you need. So far, 1/4 of the recommended amount seems to be just fine for a single brisket, with the exception of the brining step, which should be calculated based on your water volume. For that, I have a large foodservice bucket. I'll put the still-factory-sealed brisket in the bucket, fill it up with water, and then work from there. On the chefsteps site it will let you re-scale the ingredients up top, and those measurements will flow down through the page. For this, it's only really necessary to know that 1 liter of water = 1 kg. So since my bucket is gradated in both quarts and liters, I can very quickly get a weight for my water, and base the brine ingredient weights from that.
Here's a good youtube video about Aaron Franklin trimming a brisket:
I use the Mercer Culinary 6" boning knife for trimming. Comes super sharp.

I brine in a big cambro 18 quart container, then dump the brine out and cook in the same one.
I'll put the whole thing in a foodsaver expandable bag for the water cook step. All of it goes into a big cambro plastic food/drink container, for one brisket. I typically seal it 3 times per side, just to make sure leaks don't happen during the 24 hours of cooking.
For two or more, or briskets larger than 11-12 pounds, I'll put it in my fancy cooler setup. It's one of these guys, with a 2 3/8" hole cut in the top with a 2 3/8" hole saw. I use the 900w Anova sous vide appliance.
Also, instead of finishing in an oven, I'll put it in the smoker @275 for 2-3 hours, looking for an internal temperature of about 205. I use oak lump charcoal in a large size big green egg, adding some pecan chunks which have been soaked in water for 20+ minutes for additional flavor.
I'll put a foil pan with an inch or so of water in it below the brisket to help maintain a moist environment as well as to keep the temperatures stable.
I generally use either the chef steps rub or the old fashioned Texas coarse black pepper and coarse kosher salt. For this "dalmatian" seasoning, you want a 50/50 pepper/salt ratio by volume. This is basically the one thing that I prepare in the process that isn't done by weight on my little digital scale.
