A percentage is a percentage, though But I understand what you were trying to say now.
Are there any compatibility issues by installing 12.3r2 over 12.3 and/or will there be issues with updating from 12.3r2 to 15?
There won't be any compatibility issues, no. As far as going from 12 to 15, you can expect the need to update add-ons, as per usual with any major release.
EDIT: 12.3r2 is x86 only? If it is, then I'll continue using 12.3 as I'm using x64 and have no desire to shift to x86.
Ah yes -- sorry, this will be for x86 only, the x64 one didn't have the speed regression I was trying this for. So indeed it's off-topic for this board *slaps self* and a bad suggestion for you.
