Notes to table:

  1. 3yo and 2yo classes have ranges of class weights over horses' year (from August to July the following year) specified in a format comprising: August class weight in kgms followed by a hyphen followed by the class weight in kgms for July the following year. The difference between lower and upper bounds of each range, rounded to nearest 0.25kg, is spread evenly month-by-month across the year and added to August value.
  2. The optimised upper end of the 2YO R0 range is higher than that for 2YO R1 and 2YO R2 classes perhaps reflecting the quality spread of horses starting racing as 2yos.
