Inconsistent example about Fibonacci benchmarks

There is something wrong with the story about Fibonacci benchmarks presented in the compiled view here https://dave.cheney.net/high-performance-go-workshop/dotgo-paris.htm

First, you have the example of an unoptimized Fibonacci algorithm

func Fib(n int) int {
	switch n {
	case 0:
		return 0
	case 1:
		return 1
	case 2:
		return 2
	default:
		return Fib(n-1) + Fib(n-2)
	}
}

Despite it is wrong and provides incorrect result maybe it's made intentionally. But then you have a slightly optimized version on the paragraph 2.3.1. Improve Fib

func Fib(n int) int {
	switch n {
	case 0:
		return 0
	case 1:
		return 1
	case 2:
		return 1
	default:
		return Fib(n-1) + Fib(n-2)
	}
}

It's a correct working version of the algorithm but they are equal from the performance point of view, so the point about some optimization looks strange

There are no slides

There are no .slide files and therefore present does not work. Neither the local version nor the online version linked in the readme work.
