Pengo, who's the "better" rider?

Rider A: 1000 rides, 100 winners, $10 average SP all rides
Rider B: 1000 rides, 100 winners, $20 average SP all rides

Using a rider's strike rate in isolation from their chance of winning on a mount could lead you astray. Your idea has leg's though I think.

PS: Fabian Alesci won on Bombay Express at Terang didn't he? I'd double check the accuracy of those strike rate figures too if I were you.
