A number between 0 and 1 can easily scale to whatever company you have. A number that is different depending on how many is on your team is harder to compare between teams. I guess it depends on if you ask a programmer, administrator or mathematician what a logical system would be :-)

For sure! The simplicity of having the same ideal bus factor for all sizes definitely appeals to me, but maybe due to familiarity, I think I prefer the well-defined units from the version I cited. It's a bit of a https://xkcd.com/883/ situation in terms of how bad your imagination is for what "maximum suffering" would be.
