not if the update times is random throughout season which i'm afraid that's the case
i don't object to this shared scout list hypothesis
if auction list is shared so it's not hard to think that scout list is also shared
but in order to be certain we need to make sure by checking the news
if there is news that day that says you have new scout list, then we cannot prove this hypothesis
and also one more thing, if you buy scout today, then tomorrow there's gonna be another player filling that gap right?
but if your scout list is shared between many managers, i would think that your list should be empty and updated more often..
