To all: Speightstown was the third leading sire this year in gross earnings and has so far gotten 8.7% stakes winners from foals (41 of 471) which is way above the majority of leading sires which are mostly in the 5-7% range.
Interestingly, Speightstown has Buckpasser as his third damsire and therefore will receive on the average around 12.5% of the genes that were present on Buckpassers Powerful X chromosome. Of course there are other contributors to Speightstown as well like Storm Cat his BMS and Gone West his sire etc. But I always look at the influential Buckpasser in the X position as a major factor.
Empire Maker the 2nd sire on the list and Tapit the fourth best also have Buckpasser in the X passing position.
speightstown excels

And that is due in major part to the accomplishments of Reynaldothewizard which have nothing to do with Buckpasser's X chromosome since he's male and his only X comes from his dam, Holiday Runner, who has no Buckpasser in her pedigree.
David Dink recently posted a two-part, statistics-based analysis of The X-Factor (Large Heart) Theory that is of some interest in the context of the OP's notion that Buckpasser's X chromosome might be a "major factor" in the success at stud of Speightstown et al. Dink seems to think that the only "power" of the X is of the imaginary variety which is pretty much what the more definitive genomic evidence proves.
Stan,
I noticed Speightstown .#1 on Bloodhorse ' sire list this week, looks to me like there really is something to that Buckpasser X thing you talk about. So far all the arguements against have been unconvincing due the fact so many of the very best stallions have Buckpasser on their bottom side of the pedigree.

The 'Buckpasser X thing' has about as much merit as the idea that inbreeding to the Phalaris sire line is the primary cause of "unsoundness" in the contemporary TB and, apparently, is equally appealing to less discerning students of pedigree. Have a look at stallions who've been at stud a while but whose names have never appeared on any top 100 sires list (in other words consider all available information, not just that which confirms personal bias). Buckpasser is a not infrequent fixture of X passing pedigree positions among the not so 'very best' too.

It should be noted here that the 471 figure is for named foals and yes the percentage is very high, however, if one looks at the superior runners listed on Sprightstown's page in the Bloodhorse Stallion Register, they list 27 superior runners, only 6 fillies make that list and could be considered as exposed to some of the genes carried on his X chromosome and being out of a daughter of Storm Cat, the leading broodmare sire as of this post, Sprightstown also carries genes from Secretariat's X chromosome. It is impossible for you, or anyone else for that matter, to determine what percentage of genes and where they came from are present in any horse just by reading a pedigree. If Sprightstown's X is so powerful why is it that his sons, who receive no X genes from him, far outnumber his superior daughters who do receive his X?

Stan,
Speightstown is #1 stallion in the Northern Hemisphere this week. You predicted his excellence as a sire beforehand. Stan is a veritable pedigree prophet
The charlatans and false pedigree prophets sure are angry, but it doesn't change the fact; Speightstown is #1 stallion in the Northern Hemisphere this week. Good call Stan!

All this talk about Buckpasser and yet no one mentions the significance of La Troienne via Buckpasser in Speightstown, and La Troienne in the dams of Speightstown's progeny?
Come on folks, don't fall into the 'male centric" delusions of Dosage and Nicking theorists - in the end success is more about the mares than the stallions.

A difference of opinion is what makes horse racing and missionaries.
