Are female horses really smaller than male horses and do larger horses (fewer strides per second) really carry weight better than smaller horses. If they do then identifying them early will pinpoint horse with the ability handle weight rises more efficiently. It would also seem that a modification on average stride lengths per distance will be needed. At the moment there is only AW racing and although Southwell and its more demanding surface presents a spanner in the works, grass racing and its different goings will prove problematic unless I allow for them. You cannot compare a horses strides per second on heavy ground with a stride per second average for all horses across all grounds.
