I am wondering, why some papers are using IR drop correction while others are not using that correction.

1- When TO Do and when NOT to do IR correction.

2- On the GAMRY instrument, there are two types of IR drop correction, (PF)Positive Feedback or (CI) Current Interrupt. Which method is preferred for electrocatalysis, specifical when using active materila+CB+ Nafion loaded on Ni-foam as a support?
