A2 would not be expected to get 10% of US total milk market share, (at least not soon), but could look to 10% of the A2 market within a short period, so 10% of $4.8B US, i.e. $480,000,000 (AU$681M) with a 10% growth rate as above due to A2 sector growth, i.e. $48,000,000 p.a. (AU$68M).  This would be with normal marketing.

We know from AU that fresh milk will be taken to by those of gentle tummy requirements and of Asian descent quite quickly with the growth being higher than 10% yoy as word of mouth gets around.  We also know that IF in the states, whilst controlled by a couple of very large players,  (one of which is run by a UK chemical company...ooooo yuck....lol)   would be a lucrative market once the brand was established/recognized.

So we wold potentially have a 1/2 Billion market in Fresh milk wit whatever IF can add to it.    Not to shabby.
