I believe they do count exits. But it’s just that they count if you were in the ground at any point during the game.Oh, for sure, it's just us nerding. Sorry to drag it out one more time.
But this begged for a follow up...
Not really, they count the number of new entries, but it doesn't go down with exits. So the crowd for game 3 on Magic Sat/Sun is always given as > (sometimes =) to the crowd for game 2. Even when that's clearly not true, like this year. (Inevitable that the crowd would be bigger for Panthers v Broncos at Sun 4pm, than for Storm v Raiders at 6.30)
so in a 3 game magic round, most will still be in the ground at kick off for game 3
