I have written that have compiled my own Leading Sires Tables for the racing greyhounds for the whole of Ireland since 1978 but as I have not got the relevant data before 1978 I have had to use any information that subsequently came my way to enable me to compile a Table for the British Isle as a whole.
I wrote everything down to help my memory and I was able to compile a Leading Sires Table for the British Isle as a whole also for the year 1971 and I was able to access 4 generation pedigrees of 60 racing greyhound individual winners of feature events that where produced by 35 different racing greyhound sires.
Well I would have found the name of a greyhound called Hi There on the parental sire lines of 33 of those feature event winners and those winners were produced by 16 sires.
I would have found the name of Champion Prince on the parental sire lines of 12 of those feature event winners and they were produced by 9 sires and the other 13 feature event winners did not have the names of either Hi There or Champion Prince on their parental sire lines and they were produced by 11 sires.
Now the most successful sire in 1971 was a greyhound called Spectre http://www.greyhound-data.com/d?i=218720 and he produced 5 individual feature event winners and only two other greyhound sires managed to produce more than 3 feature event winners and they were called Newdown Heather http://www.greyhound-data.com/d?d=newdo ... &x=22&y=14 he produced 4 feature event winners and The Grand Silver http://www.greyhound-data.com/d?d=the+g ... r&x=18&y=9 who also produced 4 feature event winners, very similar to the results obtained for 1970.
The well known American thoroughbred pedigree analyst Rommy Faversham wrote in an article called Drawing the Lines which was about the fading and flourishing of sire lines http://www.equicross.com/drawing_the_lines.pdf in the June 3rd edition of the Thoroughbred Times.
That through history in fact, the lines of many important stallions suffered and eventually faded when their daughters (or their son’s daughters) produced sons that became better sires than those of their own male line.
Virtually all of the English sire lines St Simon was in competition with were furthered by his own (and his sons) daughters.
Consequently his male sire line faltered in England, only to be restored in America (through the importations of Princequillo, Gallant man and Ribot).
I claim that this is the cog that has turned the wheel of thoroughbred similar evolution from the mid 18th century up to the present day and also I claim that this is the cog that has also turned the wheel of racing greyhound similar evolution from the mid 19th century up to the present day.
I am not sure about his quote of producing better sires than those of his own male line but I can write that arguably the greatest example of this in thoroughbred evolutionary history is the production of Pharos https://www.pedigreequery.com/pharos, Sickle https://www.pedigreequery.com/sickle and actually Doncaster https://www.pedigreequery.com/doncaster .
