Does the duct tape ball disappear after a single use on Strobovski? If it doesn't, it might be more efficient. If it does, then maybe it is for if you miss Strobovski that you can pick it up and try again.
It does dissapear after one use. I have not missed with it before though so idk about picking it back up. I never really miss with the muffin though so even if that was the case it still seems kinda pointless to me.
