A measurement of "inflationary pressure," or value created per day
There are a couple ways to do this. (price)*(Coins per day) = inflationary pressure, or you could choose to get more specific about the number of coins produced in the past 24 hours, etc.
This kind of a measurement is useful to see how much value is being created out. Higher numbers = harder to sustain, lower numbers = easier to sustain
Was added sometime ago as part of the inflation chart
