ADuC7061 ADC5 bias voltage with single ended conversion

Hi, the data sheet of the ADuC7060/61 says on page 47 that with single ended conversion the pin ADC5 must be biased to a minimum voltage of 0.1V. Why not 0V? We want to measure against GND.

 

In fact, our 5 year old design has ADC5 grounded (via 100K) and seems to work fine. Should we change that? Is it better to tie the pin to V+ (2.5V)?
