Atlanto-Styloid Space measurements

I recently had a cone beam computed tomography image done measuring the styloids again. This time they put the atlatno-styloid space in the report. I can’t find anywhere what a normal/average space is.
R styloid is 32 mm and space is 2.98 mm
L styloid is 34.66 mm and space is 2.8mm

Anyone know what space is good?
