For the broader parameters, the percentile for each of the sub-categories is calculated, and then the mean of those gives us a final leaderboard with respect to all the players in the mentioned cut-off. For example, for volume, the first broad category, the mean percentiles of the total runs scored and wickets taken have been calculated with respect to all the 3281 Test cricketers to date. Sachin Tendulkar (15921) and Muttiah Muralitharan (800 wickets) top the respective charts. Kallis, who is the fourth-highest run-scorer in Tests (percentile: 83.47) and bagged 292 wickets (percentile: 36.5), tops the overall list here out of the 3281 players courtesy of his stellar double. By adding his two percentiles together and dividing by two, he comes out with a mean percentile of 59.99. This value ranks the highest among all 3281 players, and grants him a perfect score of 100.
