My spotter missed a call of a car inside until it was too late. Is there any adjustments for this?

He called it just as I came down in turn 4 of the Texas Speedway (NASCAR) in the Trucks iRacing series. I hit the nose of the inside car and spun out.

The spotter called inside just as I was hitting and being turned. The car that closed inside was not fast, he just nudged inside by a nose.

I am wondering if the distance setting number for the spotter to call adjustable? Is it based on a line perpendicular to the rear bumper or what is the angle it uses when in a turn? And how far away on inside or outside does it activate?
