strongly urging you to consider m% and u% instead of MIP for share allocation notation
m% and u% look like math symbols and fancy notation and is not 'pronounceable'...
Either of the notations have the problem that they're mixing percent and engineering notation: m% is 5 decimal places, u% is 8. Those are not numbers that people are used to. I strongly suggest abandoning percentage altogether, and just use engineering notation:
MIP is 1,000th of supply, UIP is 1,000,000th of supply, NIP is 1,000,000,000 of supply (if needed). Please don't make people think in terms of 5 and 8 decimal places.
And I agree with bytemaster, m% looks too weird.
