You have no understanding of randomness if you think that 100 is equally random as 212 in our decimal system. No, not every number is equally random, no matter how often you repeat it.
I understand you have a fetish for numbers that are multiples of ten, but that doesn't make them special. Picking a number out of a hat is as likely to be a 9 as a 100.
So we use fractions of 100 instead of fractions of 10 because base 60 was too useful? How does that make any sense? The question wasn't why we use base 100 instead of base 60.
