While I'm very skeptical of the achievements of young Mr. Mushtare, since there can be no proof either way I say whatever, let him have the claim. It's just going to make it harder for him whenever he decides to leave daddy's bowling center and compete in front of other people. The more miraculous accomplishments he claims in the privacy of pre-bowling, the more expectation there will be on him to "put up or shut up". The court of public opinion will sort it out. If he succeeds then doubts will get pushed to the side, if not then he'll have his 15min and be forgotten soon enough. Either way it doesn't matter much to me.
