Here are a couple of pictures from the hail pad. On the official report, I entered an estimated 360 indentations. I got the number by blocking off a 2" x 2" portion of the pad and multiplying to get a rough estimate.
I also estimated the largest hail size based on the photos and the largest dents on the pad. There was a giant dent in the upper right quadrant of the pad. It is easiest to see that on the photo with the flash.
