Haha. First, Welcome to 420 friend.
There's really no way to tell, it depends on what kind of bud it really is. If it's really dense heavy nuggets or if it's really fluffy light nuggets.
From you saying the nuggets are the size of skittles, I don't know how good it would be. When I pick up ounces I get big buds, one bud would weigh 1/8th, some buds weigh 10 grams. So if I break it down to bags, my 20 bags would be like 1 nugget/bud, or 2 nuggets/buds and would weigh a gram. That's for the dense heavy buds, of course if the guys only picking up an 1/8th of the same stuff he'll probably get it in smaller buds.
At the size of skittles with this bud you would probably be looking about for the same, 4-6 nuggets about, that's my estimate.
As for the highest quality stuff we got, you are more likely to get smaller buds in that. I won't even get a full ounce just a 1/4, 1/2, or 1/8. Some buds are 3.5 alone but usually a lot of smaller buds. Usually my 20's of this stuff would be 1 nugget or buds, 1 2 or 3. I would say they're bigger than skittles though.
At the size of skittles with this kind of bud you'd be looking at 4 or 5 nuggets maybe 3, that's my guess.
