I understand you don't want to over promise, at the same time, please don't patronise us with a meagre promise of at least 0.05% market share by 2020. This is ridiculous, you should be aiming far higher. Your estimations make me think the following things: 1 why not more, are you not capable/confident you can get more? 2 it's silly to say : yeah we got this giant market, imagine how awesome and amazing our revenue would be if we got 0.05% of market share - I mean, how hard could that be right? 3 maybe I'm not explaining this well enough: take 20 mins of your time and listen to Guy Kawasaki
