a plus for software (again)

I used my new Swift FX last night for the first time and was not aware of any leaking. With my softgel I was adjusting periodically during the night when I would feel air blowing on my eyes or out the bottom. I was excited about it since it was so comfortable but then looked at the data this morning and had crazy leaks. I am not sure why I didn't feel them but I would never have known had I depended on DME.
