Take for example graphs of Razor in his details page. Those graphs for a day show his price has been over 300 - which is not true atleast reflecting the minimum price that he is sold.
So, what is the logic behind the "graphs" that are shown to us. Minimum price is the logical assumption - but that is not the truth. What is? Are they simply "made up" - or averaged from the certain number of lowest prices or ... what?
Please give your opinion. For now it seems those graphs are totally useless for anything.
@hal2_fidelity - cannot be true, since I've been keeping razor at 300 limit and none has bulk-buyed him for 2 days - yet the graphs show that his price has been over 300 even today. Which is definately not the truth
There is en masse razors below that limit, so "averaging 5 minimum prices" would not make the price still over 300 - so the averaging logic would be extremely flawed - aka that stat couldnt be used to anything purposeful - to produce over 300 price.
This lacks a logical explanation so far (I have my doubts but I shut up about them for now.).
I doubt this, but will check up on other cards. Those million -deals are definately not affecting the price at the level they are presented, otherwise the market would show spikes like 10000 for basic cards (because single large value can affect so much the AVG price).
There might be some sort of limitng logic involved. But the point is: Graphs are fundamentally flawed and dont reflect anything straight-out usable information.
They are useful, just not for the cards that get sold in big masses. especially with bulk sales being redirected to the auctions.
also as already mentioned some high priced cards could pretty much destroy the statistics.
they are however useful for long term statistics. some cards, especially cr have a kind of circle they are going through.
