Should we look at the second derivative (the rate of change of the rate of change)? This might help us do a better calculation when we get to low values. If our second derivative is relatively consistent, then maybe low rates of change still result in high benefit? Could we just keep a running two week second derivative or something and see how the current day fits in?
