Hmm, it was only intended for use with the coupled igt test. Mind
expanding upon the use case you have? Could you not use that iterative
search for finding the injection value you want for repeated runs? For
the bisect case, do you not want to keep it iterating over all in case
the value changes? How stable do you want the modparam?
