There is no need for me to have visited or met Mr Powers and no insight required . None of these have any impact on the likelihood or intentionality of the putative alignment , or the fact that moving an object 25m has little difference in regards of the azimuth at a distance of 2.5 km . You described the situation "has yet to be recognized, despite it being one of the most outstanding alignments in Ireland next to Newgrange. " I have tried to explain why it may not have been recognised , maybe others just say nothing realising that you tend tend to get flak if you explain these things .
