Again only using NZ's top 10 so that comparisons can be made.
Mark/Nat combo has 22.1% winners but there are some very good ones in those for the prizemoney percentage is 41.8%
Top 3 trainers 65.4% prizemoney.
Again as Kevin has warned, these figures are only top 10 totals not the total pool.
Interesting the 22.1% winning strike rate of top 10 winners total.
