If you had to estimate speed during the "darting" how fast. Or to put it another way, how many degrees of arc would you estimate it traversed during that dart and in what amount of time?" Using your thumb at arm's length to represent roughly 9 or 10 degrees, how many thumbs did it travel? Did it take seconds, less than a second? The speed of a camera flash?
Thanks.
I would say the first time it moved 2 thumb lengths. I didn’t see it move that time it was just in one place and then the other. The second time it probably moved 3 thumb lengths and it seemed to leave a trail. It was moving at an angle away from us so it was hard to judge. It was less than a second but slower than a camera flash.
