I have also wondered about this so I researched it and came up with .... nothing :( It seems that companies do it because they have done it for a long time. In the UK, the proof is not twice the percentage as it is here in the US. It is a 7:4 ratio which makes things a little different. In the US it is required by law to put the percentage, but not the proof. Pointless for proofs I know, but what ya gonna do?

Why it is important to know the right percent strength of solution?
Knowing the right percent strength of a solution is important because it ensures that the solution will be effective for its intended purpose. Inaccurate percent strength can result in the solution being either too weak to be effective or too strong and potentially harmful. Proper knowledge of the percent strength also facilitates consistency and reproducibility in scientific experiments or processes.
How many ounces of 15 percent percent alcohol must be mixed with 23 percent alcohol solution to make 100 ounces?
Let x be the ounces of 15% alcohol solution. The amount of alcohol in the 15% solution is 0.15x, and the amount of alcohol in the 23% solution is 0.23(100 - x). Setting up the equation 0.15x + 0.23(100 - x) = 0.15(100) solves for x, which is approximately 38.5 ounces of the 15% alcohol solution needed.
What is London proof strength and what will be the proof strength of 100 percent Alcohol?
London proof strength is a measure of the alcohol content in spirits, defined as twice the percentage of alcohol by volume (ABV). Therefore, 100 percent alcohol would have a proof strength of 200 proof, as it contains the maximum concentration of alcohol possible. This system is primarily used in the United Kingdom and is less common in other regions, where different proof systems may apply.
