I like your concept, but for the most part, cost seems to have a minimal impact on where the overall ranking ends up. The highest rated blades (based on squires ranking) all remain at the top and the lowest rated at the bottom, with a couple blades in the middle moving up a spot or two. While the cost scores are objective, squires are very subjective. I don't find a Feather 5-10X better than some of his low ranked blades. If you had a larger group ranking the blades independent of cost and took an average, I would find the scores more meaningful. For me, I would like a way to compare what I consider to be a top of the line premium blade ( for me, this would include a Super Iridium or Med Prep Personna ) to one of my favorite "budget" blades ( Astra SP, Personna Lab Blue ) and a good mid-priced blade (Voskhod). If nothing else, a simple formula where I could plug in my overall blade score, price per blade and shaves per blade would let me compare them.
