A few posts up, there are more details about what I'm talking about. However, if you are a "POIDH" type person, you will be let down. If I was preparing a dissertation for academic purposes, then I'd have recorded all of this in pictures and a document. And besides, even if I did that, many closed-minded people would just draw whatever conclusions that fit their narrative anyway. I recommend you try looking into it yourself. Look beyond just the one sale where you undercut by 50% and something sold quick.
And I'd love to see the "citations provided" for any of the "undercutting by thousands of gil is better" posts. Since the only thing lacking more than those citations are the thought processes that arrived at such conclusions.
