Note that I purposefully didn't have many actual sales and also had large racketeer offers at either end trying to budge the prices. Common items like p ess, runes and ores should also have a 30 day historical as part of the voting. So each new day counts the votes from past 29 days as well - this would help stabilize price trends. Luxury items like barrows, whips and godswords should have a 60 day historical as part of the voting. So each new day counts votes from past 59 days as well. Rare items like party hats, santas and halloween masks should have a 120 historical as part of the voting. So each new day counts votes from past 119 days. New items Jagex plugs in a ball park figure and 'copies' it backwards into the algorithm for 29, 59 or 119 days depending on its class. As time goes by, actual market behaviour (ie voting from sales and offers) replaces the data, day by day RuneScape Addiction: Cheaper Than Coffee
