If one is shooting in raw, they may be interested to see if there is any benefit in using intermediate ISO settings, such ISO 125, 160, etc.
There is, however, no single answer to this question. Why? Because everything depends on how you implement these intermediate ISO settings in the particular camera. Sometimes they are implemented the same way as the main ISO settings, but sometimes they are the result of certain manipulations, such as digital multiplication.
We are going to take series of shots varying ISO settings from the lowest to the highest using, of course, every intermediate ISO setting available. The subject of the shots doesn’t matter – hell; you can even shoot with the lens cap on.
