That skeet is obviously hacked...
It would be nearly impossible to get a decap with a skeet like that with 100 dismemberthreshold (checked the textfile). Pressing E a frame before the decap occurs doesn't yeild a decap either.
Did you really expect a decap at that speed? No offense, but if dmthreshold was lowered i would have broken my leg only by rising it, so it HAD to be hacked
Edit: Is there a rule against hacked replays?
No, hacked replays are fine. But they're generally looked down upon in events and world records. It would have been fine if you stated that the replay was hacked in your post
