There have been heaps of discussions regarding mechanical systems. Here is one that you cannot say is back fitted as it only has 4 simple ideas which are used by most punters,


Race Distance: 1600 - 1600
Day of Week: 7 Sat
TAB Number: 1 - 3
Days to Last Start: 7 - 7

I will not post results but will say that for the past 2 years it has shown 26% POT with a 21% strike rate all states and tracks. A little fiddling will improve these figures.

I hope this creates some positive discussion as there has not been much of late relating to systems..

Remove the day criteria, add two filters (API and Age) - nice system

Another twist on this is

Same Distance, Same Track, Same track conditions, 7 days last start and winner.

Basically any winners who won under the same conditions last week are likely to win again this week.

I believe Baghwan posted this one a few years back.

The original rules of this system makes a profit in 2012 and 2011 but a loss in 2007, 08, 09 and 2010.

I suggested something like this a little while back. A good filter is that it must have had a spell in its 6 character form figures.

METRO
TAB 1 TO 3
1600m

Barny can you test with the additional filters API 1 to 3 and Age of horse 5-7

LOT 16.81%

sorry last question. Comparing my data

What figures do you get from the period

1st Jan 2008 to 31st Dec 2012 - including api 1-3 and age 5-7
