With (relatively) high speed video and a bit of math, I calculated the reaction time of my GBB to be 25/1000 of a second.
Explanation:
Video shot at 120 fps is four times faster than normal 30 fps video which is what my iPod touch records at and it still makes the final video at 30fps. The spider reacted to the cricket falling in slow motion at 1/10th of a second according to the video which at 120 fps, equates to 1/4 of that in real-time. 1/4 of 1/10 is .025 or twenty-five thousandths of a second.
That's ten times faster than the average human reaction time of 1/4 second.
