Target self destructed right in front of my eyes

The video is selfexplanatory, and this was another attempt to make a 50 knife consecutive throw for my level 1 Certificate. I failed again due to bad targets. but that is the best that I can get, so I just improvised and kept going, and destroyed two targets, and the best one cost me 400 and lasted four days, this one last 1 1, 2 days. Failed again, I am not sure where I will go from here, but I have a fine throwing knife that I designed and made 10 for this exam.
