No Stats alone are not misleading - if the data is flawed then the stats are flawed and the decisions ensuing are flawed.
What it does highlight yet again how important it is to standardise the measuring of track ratings (essentially firmness) across the country and to enforce Quality Control standards. I would have thought that this would have been one of the prime responsibilities of NZTR, the National Track Manager and local track managers. Even Horse Welfare and Safety have a need for accurate data.
The NZ data Massey University used in their report is suspect at best.
