http://cs.bloodhorse.com/blogs/scot/archive/2009/02/06/the-flip-side-of-the-bold-ruler-synthetic-tracks-study.aspxA couple of days ago we looked at how much influence Bold Ruler has had on Thoroughbred racing's top synthetic sires. So the question now is: are his bloodlines less present in poorer-performing all-weather studs?enCommunityServer 2007.1 (Build: 20917.1142)http://cs.bloodhorse.com/blogs/scot/archive/2009/02/06/the-flip-side-of-the-bold-ruler-synthetic-tracks-study.aspx#30754Tue, 24 Feb 2009 19:20:14 GMTb1464f20-99eb-45e5-b651-41da03ecff36:30754Kim<p>Interesting but statistically on shaky ground.</p> <p>You seem to be making the assumption that all stallions have the equal likelihood of their offspring running on synthetics. &nbsp;In reality, stallions in regional markets where synthetics are prominent will have a larger percentage of running/winning (or not) on synthetics. &nbsp;Look at the leading synthetic sires for 2008--Tribal Rule and Benchmark. &nbsp;Regional stallions (CA) where synthetics are the norm.</p> <p>With that in mind, you might want to try performing this analysis on, say, California stallions only or Kentucky stallions only. &nbsp;With California stallions, it&#39;s pretty fair to say that their get have an equal opportunity to run on synthetic as any other stallion in the state.</p> <img src="http://cs.bloodhorse.com/aggbug.aspx?PostID=30754" width="1" height="1">http://cs.bloodhorse.com/blogs/scot/archive/2009/02/06/the-flip-side-of-the-bold-ruler-synthetic-tracks-study.aspx#28567Sun, 08 Feb 2009 17:03:03 GMTb1464f20-99eb-45e5-b651-41da03ecff36:28567Tizna<p>This is a fascinating study. &nbsp;The only quibble I have is the smaller size of this second sample. &nbsp;Is there a reason why you chose the cutoff at 12.5% instead of something lower? </p> <p>Very interesting that it seems to be specifically Bold Ruler who improves all-weather performance. &nbsp;Could this be because of his broodmare sire Discovery, who like Relaunch and In Reality is from the Fair Play line?</p> <img src="http://cs.bloodhorse.com/aggbug.aspx?PostID=28567" width="1" height="1">
