Nice "financial" analysis however while you're thinking in terms overall "income" versus purchase value (btw purchase value is arbitrary here as prices are set exclusively by said company ). Whereas I'm thinking income vs "cash flow" which in this particular case implies the consumption rate of the very precious resources you outlined above in your analysis. However, I thank you for calculating everything! That is good to see. Have a good day gents and thanks for your comments or thighs.
