I'd say it's more about location with nectar flows than it is the type of foundation used. They will start drawing out natural or wax faster than plastic sometimes, but once they start it's all about the same, in my experience. I'd say where your own hive is located is having a better flow than where the hive in the club was located. Another big item of importance is the population balance of the hive. The number of bees of correct age to draw wax.
20+ years, raise my own queens, feed when needed. I treat, but have not perfected varroa management yet.
