It may be because we were testing on a longish, heavier volume THS, but it really was pretty over/under. I've seen it thrown by a few different people and on different conditions. It seems to work much better when the lanes have broken down. We did not have the chance to officially test it on many conditions with analysis but the feedback is from the testing we did. You can see the bowler style in the video. (BTW, the bowler in the video is not me)
Of course, I have to assume some different style bowlers may find different results.
From what I saw, despite the very big backend, it was my least favorite reaction, simply because it was the least consistent of the balls we tested.
