Let me pull out my scrum poker card deck. It contains 0, 1/2, 1, 2, 3,
5, 8, 13, 20, 40, 100, Pi, infinity.
Pi means "it's time to stop estimating and get a snack."
I have four scrum card apps on my phone.  They all use that same
scale, with minor variations.  One is missing '100', another is
missing '1/2', some throw in a '?'.

I think that's fairly standard for scrum.  We've been doing it for
several years and I've never heard anyone complain about the scale
(though they do complain about other aspects).  I don't see a reason
to invent something else.
