Yeah, what consequence would that be? You could completely reset an item and nothing really would change besides high demand for it for a week. There is just no flow in the eco, people sit on their dupes and hope they catch some new guy yelling over cc. What goes for the G.E, it also sucks for the flow, mainly because of the undercuts. You wanna sell an item? Just place the offer 1m lower than the lowest guy. 2-3 guys do this and everyone above them can forget about selling their items for a while, unless you frequently check on your items.
About the data.. Let's start with an idea for the item sink and then apply the data to it. No reason to waste time with the numbers if you wont know what to do with them.
