Hi,
thank you for you comments let me try to explain a bit without compromising the results,.
First of all there's no timed result, no need for speed or for that fact no one does this better than any one else, since it is guessing.
the goal is to learn about decision-making,
the lighting of the bulb is random and is not always 50%, this helps understand what decisions are made when a pattern arises.
Hope that cleared it up, I appreciate the involvement and participation, and I'll try to post the results here once the paper is completed.
