gross potential revenue

I have upgraded my estimate the total sales within Australia at 30,000 units.

This is based on two factors. (1) 30,000 Asthma related hospitalization cases within Aust pa. Many are repeat people and elderly.

And (2) my estimate of a typical primary school of 300 children with say max of 4 children suffering from obvious asthma and two of those families buying the ISN product. So 2 in 300.

Approx percentage of population btw 5 to 19 yo is 17%

Aust population 23 million, so 3.91 million within the target age.
2 in 300 equals 26,000 buyers of the ISN devise.

But lets round it off at 30,000 ISN devises within Aust

At $170 per unit the total sales is around $5.1 million dollars. The devise lasts say 3 years before considering upgrading.

So that in income stream of $1.7 million per year.
Thats not profit that just gross revenue.

USA is 13.5 times the population of Aust.
Lets be generous and include the US in at a factor of 15 times.

So that's an income of $25.5 million pa or $76.5 m over 3 years.

Thats terrible. If ISN has only the potential of that on these two countries, it is heavily overrated.

That is the real reason why the MD of ISN resigned. He knows the sp is maximised.
