The point we've all been making is that such an average is not an indicator of reality as such, and is pointless.

Moreover, the ending point itself is just one data point in the range being considered for evaluation, even if the ending number is fixed, the average rate of increase computed from this value alone has no bearing on how the rates actually varied in getting to this point, and thus its probability of being an accurate representative of reality is very low, there is a reason that the use of averages has been superseded by standard deviations et cetera, for you to calculate the average growth rate you'll have to take rates at all points through the progression, not just the most recent point.
