Glad I found this thread! Really helpful info.

Flight in 3 weeks, JFK-CPH. Current min. from Y is 150 EUR to PE and 420 EUR to J. ExpertFlyer shows 18 seats available in J and over 30 in PE. Not sure what I will do yet.

Is there actual flight-specific logic that goes into the weak/medium/strong categorization? Medium was exactly 20% over minimum for both PE and J. They were very close for Strong, too. (65% over min for PE and 70% over min for J)
