Everything sounds logical but I prefer to analyze it from a market perspective.
If even 100 devices are sold in 2015, at a LOW 5x sales multiple (do some DD, explosive growth companies command much higher multiples earlier on), that's $500MM market cap or $5 per share assuming current share count the day the estimate comes out, not the actual sales (thinking Q1/Q2 2015)
In 2016 if 250 devices are sold and serviced, that's now closing in on 1.5BN market cap or $15 per share at the same low 5x sales, again, based on estimates not sales (target Q4 2015)
Given we're somewhere in the stealth to awareness phase of this stock (I think it started last fall), and mix in some emotions, we could see $20 before 2016.
Refer to this chart for some education on how these usually work, and even take DDD as a recent example of stock market runups.
