It's really easy to get caught up in numbers (myself included, I'm an engineer, it's VERY easy to get caught up in numbers...), but the practice of things can be very different than what happens in a stacked deck of cards.
For example:
My family has been running coyote hounds for at least 4 generations (that I'm aware of). Even in my own brief experience running hounds (20yrs and counting), sometimes a dog gets outran, most times he burns a coyote to the ground. Sometimes a faster coyote will get tired before the hound, sometimes a good hound will burn out before he gets a hold of an evasive (sometimes slower) coyote. More often than not, our hounds get the upper hand, and that's all I'm concerned with.
My family has also been breeding registered quarterhorses for 5 generations, and had several that we've put on the track, or sold to a track stable. I've yet to own a horse that I believe could just flat run down a deer in the wild on a regular basis. Sure, I've ran a few down with a horse, roped a few even (not recommended), but by and large, my money is on the wild deer in a foot-race, not the quarterhorse with a supposed 15mph advantage in top speed. More often than not, if you take out after a deer, they'll evade your horse with ease.
Then again, I'd also put my money on an F-150 over a Ferrari, stipulating that the race occurs across a cattle pasture, not on a track.
