Eskimo Joe, inactive means sitting in the tower for long periods of time, so autoclimbing for 20 minutes isn't a problem. If your going to be walking the dog for long periods of time, you should prolly log anyway, because, like said, your ENY goes up. We had less people flying on bish than the other teams, but have much more logged in, and because of that, we have an ENY of 15.
It's not because everyone just got done with a sortie, the number stays the same for long periods of time indicating that a bunch of people are doing nothing! 55 flying, 100 logged in. 30 minutes later 60 flying 105 logged in.
All teams have around 60 players flying, but one team has 100 logged in, and because of that, that one team is punished with ENY. That's exactly what happened today. I looked at the numbers, they are no where near the same %'s, at least not today. Bish had 105 logged in, 60 flying, Rooks had 66 flying 79 logged in, and Knits had 59 flying and 65 logged in. While the Rooks had more active players in the air, Bishop still had an ENY! Doesn't make sense if you ask me.
Maybe a better way of calculating ENY is by the number of people in-air.
