The 'Full House System' is actually an old system inherited from a late professional punter from the Midlands who had a lot of success with this system in the late 1980s. I’ve recently rediscovered the system and have been testing it since May 2019. My data shows that in the test period the system made 155 selections and had 111 winners. This represents a strike rate of nearly 72%, and the system recorded a profit of  38 points from a total of 155 selections, representing a rate of return of nearly 25%. 
 
The system requires you to access the free Racing Post racecards online or buy the Racing Post newspaper. You then have to scan all the days runners in non-handicap flat and jump races to find horses that meet the system simple criteria.
