This thread has already started in a couple of other places but while it would be nice to write a fresh introduction, I would essentially be writing the exact same thing while changing the order of the words which would be similarly disingenuous. Also, this thread will have missed the previews and reviews of the first three races so far this season which is a great shame really... Nevertheless, more traffic means more conversation which means a broader understanding of the sphere which is good for everybody so I look forward to any thought and input from the good readers. Plus, I ended up adding another season to my spreadsheet and making a neater table for the stats that matter so in a twist of fortune for the husky horsemen, this thread intro will be better than any of the others.
A spell on the injury list along with a disinclination to work during lockdown meant that I had plenty of time to compile a fairly comprehensive spreadsheet of every juvenile hurdler to have ran since the 2011/12 season. Although I would like to believe that I didn't completely waste my time and am happy with my body fat percentage being in the low teens rather than single digits, there is a danger that the research is completely misleading and ultimately useless. For example, my research suggests that Kalanisi is a hopeless sire of juvenile hurdlers given that not one of his twelve representatives have either picked up a juvenile hurdle or achieved an RPR greater than 107 during this period. Facts on the other hand will show that Kalanisi is now a prominent national hunt sire on the basis of his success as a sire of juveniles - in particular Katchit, Barizan and Alaivan. Furthermore, when looking for unheralded sleeping NH stallions whose progeny improve for the switch to jumps, I discovered that the most promising prospects are predominantly dead, standing abroad or are prohibitively expensive due to their ability to sire two year-olds.
Nevertheless, in the realm of juvenile hurdling where publicly available information is decidedly threadbare, imperfect evidence is better than none whatsoever. Particularly as the genetic attributes necessary for success in juvenile hurdling tend to be specific as there is a demand for both strength and precocity.
While an exhaustive publication of all of the findings might well be in the spirit of a comprehensive research thread, the utility of same is difficult to justify given the bulk and diversity of the information. As such, it would be more appropriate to apply the findings on a race by race basis. Nevertheless, in the meantime here are a few top-tens for the purposes of fun. Not all of the horses or trainers listed will have juvenile runners this season.
The RPR figure of 108 was chosen as it would put its achievers in the 75th percentile. The improvement rate figure looks at the percentage of a stallion's progeny that improves for switching code. The figure is reached by subtracting the lower of the horse's official flat rating or highest flat RPR from the highest achieved jumps RPR and subtracting a further thirty-five pounds. Those with positive figures are assumed to have improved and those with negative figures are not. For the sake of integrity, only horses who have raced more than twice over hurdles AND have achieved an official rating are considered so as to reduce the skewing of the figures by lightly raced sorts.

I also have stats for the 1268 horses who were sold at public auction as horses-in-training prior to being sent over hurdles from 2012/13 (I have yet to update the sales spreadsheet to include 2011/12). The most interesting findings were that based on extrapolations using mean figures, £119,860 will get you a 108.56 rated juvenile, £49,459 will get you a 97.9 rated juvenile and £3,014 will get you a 54.2 rated plodder. Also, there's a 99.95% chance that you will not recover the sales price through prize money during the juvenile campaign.
