I have already gone through the various technical notes on iR compensation available online from different sources. While most of them have discussed about the various techniques that are generally employed to know the uncompensated resistance, much information is not available on the "compensation level" and "undershoot" values that has to be used during measurements.
I understood that the undershoot primarily corresponds to the circuit stability but then what should be the optimum value? Different technical notes are suggesting different values (for example, CHI recommends 2% while others suggest 20%). I find this particularly thought provoking as this will ultimately have an effect of the observed R value. Similarly, Bio-Logic recommends to use maximum 85% compensation level, while others suggest ~90-95%.
Any source or answer providing in-depth explanations are requested. Thanks in advance.
