I think at least two weeks, a month wouldn't even really be stretching it. Like... time passes really quickly? Also it's summertime so people might also be busy doing things maybe? *shrug*

If it does turn out that suddenly almost everyone's caught up to precent day and impatient for stuff to move again, we could start time again earlier. I'd rather do that than to make people feel rushed.

Also yes I think a 1:4 ratio would be good.
