Here's some examples of the differences in sticking to flat races.
Last start winner within 7 days raw...
18.66% S/R
4.84% loss on turnover
But this also included a winner @ $47.90, so if that didn't occur again the loss is greater.
So we click Modify Search and in the Closing Price, we consider horses that are under $10.00 on the tote.
Requests -> Add New Request.
Click the Omit button on the toolbar and in the race class box type Hurdle.
And again...
Requests -> Add New Request.
Click the Omit button on the toolbar and in the race class box type Steeple.
Hit the green Search button.
26.51% S/R
2.50% POT.
We then get Top Fluctuation or go to Betfair and get the extra 5% to 15% after commission.
There are other filters that improve this, but they are part of the systems included, so I can't post those.
But for those with the database, this shows you how to omit something from your search.
I've endeavoured to keep the speed of the database optimum.
I compared it with another commercially available database.
RaceCensus to 28 seconds to search for all favourites and do all the calculations of strike rate and profit & loss.
The other took 3 hours!
Note: to be fair the other calculates ratings etc, but a simple favourites search would leave me pulling out my hair
