The $800 million recurring revenue goal only assumes 50% market share in 3-5 years. They are saying that by just achieving and maintaining 50% market share, they will get to $800 million as a result of the volume growth over the the next 3-5 years.
The best explanation of this revenue goal was provided by James Nolan at the Cowen conference. He did a great job at this conference and for those who have not heard it, I recommend you listen to it.
