beboper, let's use pm grinis black dragoon as an example. pwr 18 card, atk 13125, def 15225, skill is great boost to water/fire def. based on the table above, grinis should be selling in the range of 40-50K because it's a pwr 18 card with over 15K def. BUT...last i checked, a RM grinis sells for 70K, so a PM grinis would be 140K! which is almost 3 times the highest selling price of 50K.

if we use your base price of 50K, and factor in an inflation range of 2.5 - 3.0, we can roughly calculate what the market price might be - take the highest base price and multiply it by the inflation factor (so in this case, grinis would be in the neighbourhood of 125K (50K x 2.5) - 150K (50K x 3).

the main idea is that you keep the "base" price range, and adjust for any price increases by multiplying an inflation factor to it. this would remove the need to "re-price" a card in the table every time price jumps. not sure if this idea can be implemented or not. just throwing this idea out to see if it might help. thx
