So what is your point? This thread was about a human being able to outrun animals.
I was using a perturbation theory approach to the "one human, one predator" scenario.
Even if the predators can catch one person--would the sustained-high-average-speed of people work if they were in a group?
And the fire remark was meant to show that people don't need to rely solely on running away.
Nowadays, they can use a rifle.
Cheers!
