Attenuation Scaling Factor (UE4)

Question

I have a question about the attenuation scaling factor variable in the akcomponent. I am having to set it to values upwards of 100 for even quiet sounds like campfires. Is this correct? Should my sounds be better calibrated inside wwise? I'm not sure what the standard is, what's more physically accurate and what I should be aiming for with that value.

Thanks in advnace
