doomster I have been looking at system's since around December - have to say through a very cynical eye - but I can now see blue sky ahead - the problem I have, is the stats and how to value ones use against the others - but now alighted on the most relevant one's to me at least - bearing in mind the ups and downs that can befall any horse and jockey in running - stable health etc - I think you need to have plenty of margin on side and some further rules (that cannot as yet be applied by the data bases) before diving in
System creation parameters
No 1 has to ROI BF - want 30% min - No 2. SR want to 18% min
Further some on the day pre backing checks
Beware of races with multiple trainer runners - Draw Iv and Pace of race - WS need a check -
Finally but most important - is Min Price
Your above I assume these Figs are backing all blind

A Mullins system would be great at Clonmel - Belestown - Tipperary - Promising at Galway Limmerick Roscommon
I would need to looks at months and various other stuff but there is clearly something to work with
