I also note the stats on that site also list LR races as well. Just sitting here looking at that site and run a search on the first horse mentioned in those stats, Temple of Boom. The win mentioned there was a Group 3 race on 6 August 2011, at its 4th run back from a spell. The very next preparation it won a Group 1 race also at its 4th run back from a spell on 21 April 2012 at 14/1.

I've looked at things like this on and off over the years, never really only just concentrated on Group Races, usually just run of the mill races and it was very time consuming.

Something to store in the back of my mind here,
