To the original point, as others have said, lots of variables. Not letting manmade leach is an all too common fatal mistake in the industry today, with its apparent obsession with instant gratification. Me? I'd rather make snow in a wide distribution (more labor, ergo more expensive, ergo not the favorite of most mountains), and still give it 48hrs to leach before touching it with a cat.
One thing I will say about Sugarbush...they are a big proponent of not touching fresh man-made snow for at least a couple days usually before grooming. They might make exceptions if there's an urgent need to get a certain trail open and skiable for lower skill skiers or if weather or holidays force their hands a bit, but it isn't uncommon to see trails with whales on them for several days before they groom them out.
