I think that there could be a situation, very specific one, where the ETP could be outside the ENTRY, EXIT point, so as mentioned not between them. how it could be possible? as we know, the ETOPS circles are made according the still wind rulez, so the wind is 0, but the ETP is actaully taking the wind into acount, so there could be some special cases, teoretically where the ETP would be slightly after EXP, I think that I saw that once in my life, and was wondering as well
but could make sence?
