I used to excel in math but now can barely do 3rd grade level (yes, math and problem solving took a big hit), this being the case, I was able to understand a majority of it and found the discussion and article interesting. For the "average" hobbyist, I doubt that any of this would matter in pursuit of the hobby. For those that like DIY, I feel this would be more appropriate to figure out the material needed for some projects as it would eliminate"guesstimation" and provide a more accurate figure to work with.
Keep up the good work! Let's see a few more articles like this.
