There is no official "retal window" but if there were one, it would definitely NOT be the whole set wtf. Farmers get a little more leeway because they're slow starters but most strats, if you can't do it within at most a week, you have very little business coming back later. Of course, if you get away with it depends on who you're hitting. CROATIA is moaning about 98 hours, what do you think he'd do if you hit a month later?
