In the CIM API, there is a strict transaction limit of 30. Now I have some customers that are DIY kit stores and some of their customers could have as many as 50 line items. I realize that you didn't want to make the number infinite or overbearing huge to help save server load, but I feel like 30 is a bit low. Maybe a more substantial number would be 100 or 200 since it is just an XML request/response.
