The Trainer Statistics report is, in fact, four reports in one. It contains information on a trainer’s recent form, and their longer term course form.
For each of 14 day, 30 day, course one year, and course since 2009, users can filter by runs, wins, places, win profit/loss and each way profit/loss.
Clicking on any row in the report will reveal the runners that trainer has entered on the day in question, and clicking on the runner row will open that race in a new tab.
HINT: It can help to cross refer the profit figures of the trainer with their win/place percentage. A few big priced winners can mean a trainer has a high profit number but a low strike rate. You may need to be very patient, and a bit lucky, to come out in front this way!
