The rankings are carried out manually from extractions received by the FEI, and significant cleaning of data is required, as well as identification of duplicate sires, often due to spelling mistakes when original data is recorded by national federations.

Therefore, mistakes occasionally creep in, despite repeated checks before publishing. These mistakes are sometimes picked up by attentive users of our website and rankings, and we are grateful to them for helping us to maintain the integrity and correctness of our rankings. An update of the jumping sire rankings is therefore being published, which moves Spartacus TN into position 37, and Action-Breaker into position 57.

A further offspring of each of the stallions Kannan and Bamako de Muze was also found.
