Earlier it was suggested to "wait" for 73 hours in the game. Not real time... in game time.
This was not in relation to scripts though, it was related to the cleanup process - furthermore, it was later proven to be ineffective since the cleanup process is only applied to cells as you visit them.
Scripts will sort themselves out as and when they are re-triggered, there will be no specific amount of time that fixes everything.
Am just booting up the patch now, will give some feedback from a TES modder's perspective ASAP.
