The Runedex and Lists pages have now been plugged into the new design. This change is effective on all browsers except pre10.0 Opera. The bottoming out and peaking lists have not been effected by this update, but they are coming soon. Also, personal Runedexes are still on their way, but this update doesn't include that added feature.
The new design allows for some additional limited multi-sorting abilities (thank Stramel for that one). Now you can not only sort Runedexes by alpha, gp, gp change, and percent change but also limit searches to only items with values above 100, 10k, and 100k. As with all updated pages, some features are still to come. I want to put filtering by f2p/p2p in place (also add it to the search pages). And listing by beginning letter (which is good for the full economy Runedex).
The Runedexes also use a new Indexing system which might seem a little haphazrd, but I think it is an effective way of indexing. I have decided to go for an indexing style that more closely matches real world stock indexes. So for those of you interested in the math and my logic I use on the Runedexes, here is a technical review of how the GEC Runedexes are calculated. I hope that this method will be able to provide visitors with logical and at-a-glance performance information about each Runedex we provide.
So the first thing we need is the total value of the runedex itself. For this post I'll use the Cape Runedex which is valued right now at 4,759,429 gp. The average value of each item in the Runedex turns out to be 62,624. Now those are some wildly large numbers. So I wanted to bring things down to something a little more manageable. Like the 1000s. But before we do that, we needed something to compare todays numbers with. So we find out the weekly average value of the runedex from 90 days ago and from that find out the average value of each item in the Runedex. From that we find out the number that magically turns that average into 1000. This "divisor" is 0.01940. Now we go back to todays average item value, remember 62,624. Using the divisor from the weekly average 90 days ago we get a more manageable 1214. Which means the Cape Runedex has increased in value by 214 points since 90 days ago. The two week chart gives a visual idea of how the Runedex has performed over the recent past.
I'm sure that all sounds haphazard. And in truth I think it is kind of wonky. First of all, it causes the index to be weighted (or effected more by changes in high value items). But for now I think it is the best simplication of Runedex values. I have thought about ways to do an unweighted Runedex for over a year and I have yet to come up with something that feels right. Until then, we'll go with this system.
