So the way I understand it, (and I could be wrong so, please feel free to correct my interpretation) Each shooting session, the models are contacted and those who are available, are scheduled for that shoot week. Then they travel to the location where the shoots take place and are housed or accommodated for the duration of the scene shooting session. During that time, several scenes are shot using the models who have made the scheduled appointment. That can result in various scene combinations. The end result is, we get scenes released in any combination of those models until the next shooting session which may include different models (be they new or available at that time). Hence, we may see scenes involving the same models during any given period that shooting session took place?
Is that a fair assumption on my part as to why certain models seem to appear in "alalmoalmost every scene"?
