title: Statistical interpretation of the Bekenstein entropy for systems with a stretched horizon.
abstract: For the two-charge extremal holes in string theory we show that the Bekenstein entropy obtained from the area of the stretched horizon has a statistical interpretation as a "coarse graining entropy": different microstates give geometries that differ near r = 0, and the stretched horizon cuts off the metric at r = b where these geometries start to differ.
