Ok lets prepare for tomorrow now that I got the stats and some time:

Sandown Lakeside.
Jockeys with sub 15% strike rates, worst to best.

Chris Symons
W Hernan (a)
Craig Williams
D Gauci
J Winks
C Newitt
V Duric
S W Arnold
D Dunn
D Oliver
J Benbow
G J Childs
C W Brown

Trainers with sub 15% strike rates, worst to best:

D A Hayes
B Mayfield-Smith
D T O'Brien
M J Ellerton
R E Laing
J F Moloney
D L Freedman

Interesting that Hayes doesn't do so good at Sandown! And he has fielded a lot of runners. Tho I think the problem is he runs more than one horse in the same race so no doubt that stuffs up the strike rate :-/
