Joltman hits the nail on the head when he points out that all that nicks services "can do is reflect the past, with the hope for the breeder that the trend is real and continue in the future." Or, as mutual fund prospectuses correctly warn, "past performance is no guarantee of future results."
Whether one puts much stock in nicks ratings or not, stallion owners and managers certainly seem to. They obviously take more kindly to mares with an A+ mating rating with their stallion and can make it a deciding factor in getting to a stallion -- and at what price.
Few real industry professionals---true horsemen---place any stock in the commercial nicking products.

Depending on what it finds ( 0 zero SW - F all the way up to A+++) it rates the mating. It does not take into account any other influences in the pedigrees. It does not take into account the number of horses where those sirelines have been tried together, or not. It is a Very Narrow Perspective. It also goes back up to three generations which, to my mind, does not jave the same validity as using just the sire and the damsire.

I don't mean the cross itself is bad, but the same people who want to see that A are going to take some convincing that a D is not to be taken too seriously. A better answer would have been for these systems to say I as in incomplete data BUT here is the next generation.
Tappiano wrote:I would counter that there are very few US mares that nick well with the European based stallions because of the sample and the fact that for three generations you have stallions who never covered a US based mare. Add in the German bloodlines and now you have even fewer to draw from. This leads to a D rating because if there are any examples, there are so few it cannot be a true representation.
A US based Danzig line stallion yields an A nick but a Euopean based one yields a D. A grandson of Sadler's Wells in this country yields an A but in Europe it's a D.

Pretty much every Forty Niner line mare is an A+ to stallions with Sadler's Wells in the pedigree in THIS country but not in Europe.
Does that work for an example?
