Here is code and comment from one of the example sketches:

Indio.setADCResolution(16); // Set the ADC resolution. Choices are 12bit@240SPS, 14bit@60SPS, 16bit@15SPS and 18bit@3.75SPS.

Looking in Indio.cpp, analogRead has delay(sample_rate) and in analogReadMode routine, it sets sample_rate based on the ADC resolution.  For example, for the above resolution of  16 bits, sample_rate is set to 67 ms, which will give 14.9 samples per second.
