These are screenshots for a flight from EWR-LHR


What makes the order change so drastically in the PP vs Polaris lists? For example CAL,F is number 1 on the PP list so has priority over all others then on Polaris list is down to 7, LIN.R is number 2 on Polaris list but for PP down to 4. ISK,O S is 6 on PP list but up to 3 on Polaris list. What makes one passenger in Y have higher priority on one list and then lose that priority on another? For reference I am #4 on Polaris list and am 1K in PP so only can assume that MET,S, LIN,R and ISK,O are GS and the other are not, but if so then how could MET,S, LIN,R and ISK,O all had at least one non-GS above them on PP list? Or do these lists just mean nothing? Is same on app too though on chatting with agent they said to me I was 5th on the list.
