Flavor ratios describe relative amounts, which are designed to stay the same when you scale the amount you’re making. If you express the mix so the ratios sum to a constant total (often normalized to one), that total stays the same no matter how big or small the batch is. So the statement that there is one total no matter the size captures this idea of fixed proportions under scaling. Saying the total would grow or shrink with size would mean the ratios themselves are changing as you scale, which isn’t how these mixtures are defined. The notion of “four numbers” doesn’t address how the total behaves when size changes, so it doesn’t describe the scaling behavior.
