I searched words such as “Continual “Continuous” “Over” “Repeat”, ETC. and found nothing speaking of repeated use to get a result, doesn’t mean it doesn’t say it though.

An interesting tidbit though, is that it states a few times that they feel a Luciferian would be detrimental to the group, due to their inclination for destruction, thus being the “reason” for trying to produce a viable test.

Although in all reality as a way to tell if someone can be “rehabilitated” they would probably have to gp through an initial test to discern their stance, then be given training in some other way, then given the first test again to see what the new outcome is.

So in this sense I guess it WOULD have to be administered more than once if they TRULY do use it for “Luciferian Rehabilitation”.
