With 4 users, the Max() is 25 for both the user limit and the capacity limit (from my reading of the source). Either pushing the example to 5 users or raising the user limit to something higher than 25 would help a great deal. Also, presenting this info in tabular format showing how the max() value is in play would also be great. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
