Added this graphic to the end of Entry #2 in the first post, this is the last thing I have for right now. I pulled out all of the subjects that had at least 10 data points to look at, that is, sales of 10 different front/off back/grade combos. These are the multipliers. None of these had a Hindu Brown sale, so I just omitted that from the chart to make it fit into the post without having to scroll a ton. Enjoy
