For sure i agree with some of what you say, but i am not looking for best price but a fair price(fair trade not capitalism) and while knowing the average gold per hour is not the only factor it can be a dependant variable to work from, before moving onto the next factors.
Yeah, this is going to be a fruitless endeavor. You're going to somehow find out the "average" amount of gold people make per hour (it's somewhere between -1 and 50) and then somehow determine "fair" prices for fake items in a video game. That will require finding just how much the average person values their time playing a game. You're going to have to quantify "fun". It's not going to be as easy to calculate "fun" as it is the minimum equivalent living wages in different areas in real life.
If you want to be the god of "fair", you're probably not going to want to use the AH anyway, since if you try and sell for a "fair" price, people with 1000s of gold will buy it and resell it for the real price.
Work like no one is watching, dance like you don't need the money...
