How long a view is needed for a teleport's "Viewed Once"

[NewJeffCT]

“Very familiar” is a place where you have been very often and where you feel at home. “Studied carefully” is a place you know well, either because you can currently see it, you’ve been there often, or you have used other means (such as scrying) to study the place for at least one hour. “Seen casually” is a place that you have seen more than once but with which you are not very familiar. “Viewed once” is a place that you have seen once, possibly using magic."

So, is it less than "seen casually"? "Viewed once" isn't studied. Consider you are driving cross country and you stop and get a slurpy from 7-11. You just walk in and back out. Was the magical viewing at least this good as far as the inside of the 7-11?

This wasn't even that good a view. I would consider it more like seeing the last 3-6 seconds of a 7-11 commercial on TV as you were flipping through the channels. Three seconds from a distant view, and then three seconds from closer.

Sounds like they are SOL.
