For sure something to consider there.
292 total starts for 40 wins.
A 13.6% WSR.
Don't know what the SP's were though.

I was actually thinking more along the lines of something like this.......

If a young horse "blunders at the start" or "knuckles at the start" or somesuch, then lay it if it starts again within say, 3 weeks.
The theory being that seeing as it's bones haven't yet knitted, it perhaps has sustained unknown/unseen injuries to unfused joints.

Dunno, may have legs.
