Reach is defined as the number of unique items we priced that day, and the volume is defined as the amount of individual prices we collected that day.
I would say we are doing pretty well so far . The prices are currently coming from SL and I harvesting items with our custom item harvester, along with users of Neon AP, and Abrosia. Abrosia is expected to send in the most prices and it is only in a private beta at the moment. Once we release it to the public, we expect this graph to take off even further .
You guys may not be as interested in this as I am .
