I wouldnt bother with any research on whats written.
Better just to take My

Grouter System

Concentrate on horses that ran 1st or 2nd LS EXACTLY 49 Days ago.

WAIT until they have 10 losses in a row then bet the 11th Race.
Then WAIT for another 10 losses then bet the 11th bet etc etc

Only too pleased to impart this .Its a oldie and was sold around 1980.
Presumably the seller made a fortune and retired and out of the goodness of his dear little heart gave it away for a modest sum.

Prior to system designing I believe he used to tip to his clients via Telegram.
