Which is true yet the completion rate for juvenile hurdlers at Kempton is the fourth best in the UK at 91.35%. The key difference is probably the fact that while the average seasonal RPRs for those competing at Kempton is 100.28 (105 median), Southwell's is just 81.07 (86 median)
Front runners do indeed have the best winning strike rate in three year old hurdles at 22.82% compared to bumper horses at 16.11% and handicap hurdlers at 13.17%. They also fare well in percentages of races won at 27.69%. The rates do drop slightly once the juveniles hit four as the win rates and percentage of races won by frontrunners falls behind those using the same tactics in handicap chases but they remain ahead of handicap hurdlers and bumper horses.
There are most probably differences between courses which I might explore once there are a few other items knocked off my to-do list. Dave Renham has written some very good pieces on the effects of pace in National Hunt races so it would be interesting to see how juvenile hurdles stack up in isolation.
I did have a look at winning DIs by pace among three year old juveniles since 2011/12 but while the median DIs make sense, the mean averages were unhelpful even after lobbing five percent off each end.
My friend likes that I am low maintenance so everybody wins really.
