OK, now that we got the rest of our order, we measured a total of 20 balls.
Average weight is 183.5 grams
Standard deviation is 2.55 grams

We unscientifically noted that balls also have different levels of hardness, and it doesn't correlate to weight. For example, our 187 g ball is a lot softer than a random 183g ball (as measured by pushing on the face opposite the hard spot).

With that being said, I don't think 3 grams in either direction will matter much.
