Airflow probe readings drift slowly and nobody notices until cup changes

Recently I have been discussing airflow probe drift on roasting equipment with several coffee people and nobody gives the same answer. Some treat it as small detail, some say it changes the whole workflow. I am not looking for textbook reply. I want to know whether airflow probe drift on roasting equipment gives meaningful difference once you repeat it over many cycles.
Would you keep airflow probe drift on roasting equipment in your normal process, or only for specific coffees and situations?

I think the bigger issue is not airflow probe drift on roasting equipment itself but whether your baseline is stable. If baseline keeps moving, then every experiment around it gives mixed signal.

From my side this helped only on certain coffees, not on every lot. When the coffee is already forgiving, airflow probe drift on roasting equipment does not change much. On difficult lots the effect is clearer.

I disagree a little with people who say airflow probe drift on roasting equipment is only a small detail. Small detail alone maybe yes, but several small details together can move the cup a lot.

What helped me most was keeping short notes each time. Without notes, discussion about airflow probe drift on roasting equipment becomes memory battle and not real evaluation.

For airflow probe drift on roasting equipment, I only trust conclusion after I see same pattern several times. One successful run can be accident. Repetition is what make the lesson useful.
