Don't let the title scare you off :P
All this is is taking the progression from the recommended wealth for NPCs, and changing it into percentages. One question I do have about this data is how this applies to actual PC wealth? Do you find that this fits the standard PC wealth curve or is it drastically off?
But first, to the data: (you can see the excel sheet on Googledocs here: NPC wealth table

So, any comments or thoughts on this?
I have made some NPCs using that chart almost exactly (some things cost less than a gold) and they were fun antagonists. Using consumables against the players often gets a reaction out of them I find.
