The data is interesting, but maybe incomplete. Doesn't look like you have quite enough information to truly understand the market.
Apologies for name-dropping a colleague's project, but you might want to look at http://validate.io for a more comprehensive, scientific analysis that's actually done by someone who knows how to design surveys and analyze data (they have a PhD design and run a survey for you, it's pretty sweet). A little more than $100 but worth it to have good data on your market. You might still avoid wasting $40k going the wrong direction, but you might be able to trust it more.
