I think it had been developed by trial and error. Northern Germany where thes bikes have been made has enough opportunity (i,e. cold and foggy days) for doing this, and i simply can confirm that it works. Just opening the front hole has a noticeable (bad) effect, and even worse when i open the hole in the damaged wind screen of my bike. Although it is relatively small, it affects the air flow within the bike massively. Which clearly shows to me that there must have been real development. You find that one in the two successor models as well (as an option, especially the Evo-R has been a pure racing machine).

BTW: here the two sucessors of the GoOne 3 - the larger one is its direct descendent:
