Doing the numbers, page-4

@hotcongo

I chose to fit an exponential to receipts and outflows for three reasons:

- It would be normal to expect exponential growth for the receipts up to a certain point as the product becomes better known in the market place

- The quarterly growth numbers are more indicative of exponential (although there is very limited data)

- I did run a seasonal average over the data - it removes too much information to be of much use - but it did come up with non-linear growth
