And that was the reason I suggested a DAC as a reference to tailor the resolution of the ADC to the measurement... Here was my original thought...

DG408 into resistor divider into MCP3201.
and to solve the Granularity issues a variable Vref (DAC) might be used to solve this:

voltage divider going from 5 to 15 V down to 0 to 5 V means there will be roughly three times less 1/3 less usable information detectable in the output signal
so change the Vref as required to increase the effective available information by providing a Vref suitable to the measurements.
@ zoomkat... Apparently then you have an attention span issue because I made this one 2 days ago...Bob
