Exactly, and like you said, in the end, it is up to the owner of the vehicle and it's tuner to decide what "acceptable" is for them. I will say that with a short ram intake, the compensations are going to be pretty difficult and fuel swings will be pretty HUGE, but with most variations of cold air intakes, they actually should end up fairly stable and accurate when compared to a setup with the sensor post intercooler.

Something to point out here is that one of the absolute worst places to install a SD IAT sensor is post turbo/pre-intercooler. The temps here will vary greatly based not only on ambient temps, but also on boost pressure and turbo efficiency as well. The compensations will be extremely hard to tune accurately if the sensor is placed here.
