Maybe someone can hint me in the right direction. Using the "not so blind" part of the challenge I manage to reduce the challenge to discriminate 6 possible "blindnesses" per request. However, the time the server let me stumble around in the darkness seems to have some heavy fluctuations. Therefore, I was not yet able to solve this one. I typically walks which scale by 0.1 s, 0.5 s, 1 s and even ~10 s (sorry to cause that much db-server load). However, I eventually get spikes of up to 4 units away from my goal.
Btw, I have a good internet connection and use curl for the timings. (Simple POST connection is around 100 ms). Do you have any ideas how to improve the current situation? Thanks!
