Maps per player stat?

So I was thinking about how the number of maps on this site has been growing steadily, and moreover wondering whether the average map gets the same amount of play as it used to, say, a year ago.
I'm basically wondering if there's any way to find out what the ratio was with every new batch of maps? It'd be interesting to know how that ratio has changed, or if it's remained basically constant.
