My questions are:
1) is the above listing correct? If not, where did I go wrong?
2) if John has eaten too many steaks and his weight went up to, say, 70 kg,
how can we:
     - tell that the weight of 68.5 kg is no longer valid, and now is 70 kg?
     - tell that, because of that, he does no longer qualify for the Welter
Weight class?
