Oddly I was faster if I concentrated on the vanishing red light (210-220 ms) instead on concentrating the lightening of the green light (240-260 ms).
I also tried out not focus (aren't the rod cells on the edge of your vision faster in detecting movement than the cone cells in the center?), but it didn't amount to much.

Ha, I love stuff like that test. I couldn't break 210ms though, 213ms was my best
You should hold the key down. I got 10ms average.
