What's the sound of a great 60 seconds pitch?

I'm wondering about the pace metric - just by listening, it seems that some of these pitches are much faster (mailchimp) than others but the pace indicator looks pretty much the same for most of them. What are the extremes of the scale? It seems in order to get a "slow", you'd have to speak at 1 syllable per second or so. Maybe narrow the range a bit?

EDIT:

And it would be cool to have some sort of summary or total score on the overview page for each pitch.
