I guess it doesn't really matter who posted it, the people that looked at it gave their vision. So why is this build the other way around? Wouldnt it be more normal to provide the blueprint and a paper and build the code based on the verified mathematics? If your developer is a so called genius then why isn't this done properly and does he need other people to create what normally is the first step in a building process?

This is like, i build a house without blueprints, don't know if i have done it correctly or that its stable, please check it. Doesnt make any sense.
