Sadly, my reply was: ''I have no idea.''
The reason why I was contacted is because my twin brother, Tony, run a study regarding the significance of pattern-race entries within two-year-old horse racing.
In fact, the data was pieced together into a story by Mordin for his popular Systems, detailed in the Weekender publication.
The article was titled: In a Class of their Own: How to Spot & Back Potential Top-Notch Two-year-olds. I can't remember the date of the publication, but it must have been a long time ago. [I found a link to the article on High Class Equine dated 14th, May 1994].
This research was groundbreaking and it was the first study of its kind in the world.
In fact, I have had many people remark about its publication years later and still holds a lot of interest and clout to this day.
My brother and I still use this information and we detail some aspects for free via our Group Horse Subscription + Easy Professional Gambler Mailing Series. (100% Free).
Nick Mordin is a man who was much respected in the racing world finding angles and writing a number of publications to help readers get ahead of the game.
Betting for a Living (1992)
The Winning Look (1994)
Mordin on Time (1996)
Winning Without Thinking (2002)
All were very well received and I have a couple in my personal collection.
I notice a few threads on Betfair Community musing about his work.
I do believe Mordin went to live in the United States although I couldn't confirm this as fact or fiction.
Many punters will remember he was criticised by Harry Findlay about the chances of Denman winning the Gold Cup. At least, I think that's what it was about as the old grey matter isn't quite what it used to be.
Anyway, wherever you are, Nick, I hope life is treating you well and my brother often mentions the phone conversation he had with you back in the day.
All good stuff.
