big IPD guy here. is there a range of IPDs that work in VR or does it need to be exact or you will eventually get a headache/sickness? before I looked it up and realized how huge my head was, I was more or less happy with the 70 IPD setting and didn't realize that it was set incorrectly. Now that I put the foam in I think it is subtly better, but I could still read text clearly and things like that

how is it possible that 70 IPD was okay for me even though my IPD is like 73?
