good question m8.
events n stuff always start when the map loads whether there is a start delay or not, so basically the start delay has nothing at all to do with map editing.
what u can do is set an event which has the peramiters of 'blue win' set on a time delay. where the time delay is the same length as the start delay.
i hope that gelps a bit but it seems ur first question is different than ur first.
i'm also curious as to why ur doing this, could u tell me? it sounds interesting
good luck
