Is AFC airflow correction linear?

I tried to search for this, but found it difficult not knowing what key words others would use.

My question is, on my AFC neo, is the airflow correction from one RPM setting to the next completely linear, or more exponential? What I’m trying to ask here is, if I have 4,000 RPM adjusted to -14% correction, and 5,000 RPM (the next point) at -15% correction, does this mean that at 4,500 RPM, my correction will be exactly -14.5% correction? Or is the correction curve exponential so it will start to lower the correction exponentially (that one percent) as it pulls closer to 5,000 RPM? This concept is similar to the EQ on stereos, so all the curves are smooth, and not jagged. I can get a general idea by looking at the correction map, but I wanted to see what you guys thought/know.

I suspect that the correction it totally linear. Let me know if the question is not clear.

The correction is linear.
