TAGHI ASKARI diving champion aged 100

It is customary to have five or seven judges – seven at certain major international events – and they only focus on how the dive has been performed. The difficulty of a dive is taken care of by the tariff. The highest and lowest marks are ignored. If there are five judges the remaining three scores are multiplied by the tariff to give the score for the dive. If there are seven judges, the five remaining scores are added together and then the result is mathematically adjusted to be the equivalent of three scores for comparison purposes.
