Oh, brill, Gareth - many thanks for unscrambling that lot! And thanks for a good try, Shadz, appreciate that. Now, please bear in mind that, following Redhead's original question, I didn't say that there were more French horses in British NH racing, but that the top yards had pretty high percentages in theirs - before anyone points out that there are lots more Irish and British beasties. However, it's interesting to see the gentle upwards curve of the French influence.
Troods: yes, I'd never reckoned on Slovakia as jumps country, tbh, but there's an interesting miscellany there, for sure.
