So finally, here it is: the data they didn’t want me to bring you.
This is a table of all 469 reviews conducted under the Umpire Decision Review System (UDRS or DRS). It shows how many were against each umpire, and how many of his decisions were overturned on appeal. Lastly it shows what percentage of his decisions were wrong.
The table is ranked in order of this percentage, a “fallibility” index. You may draw your own conclusions from it.
