Winning ages in jumps

I was inspired to do this post after reading a thread at Raceadvisor forums about ages of winners in races over 3 miles. I thought that this might be of interest so decided to calculate strikerates by age and race distance. Leftmost column is age and distances on top row. Data for these statistics is from all races ran in UK and Ireland in 2012 and 2013.

First, chase in races between 16 and 24 furlongs.

Chases over 25 to 36 furlongs.
