Lets you increase the number of virtual users during a run.
If a schedule contains only percentage user groups, the virtual users are added by proportion. Assume that your schedule contains three user groups, assigned at 20%, 30%, and 50%. If you add 10 virtual users, 2 added are to the first group, 3 to the second group, and 5 to the third group.
If a schedule contains both fixed and percentage user groups, the fixed user groups are assigned first. Assume that your schedule has one user group fixed at 10 users and only one virtual user is running in that group. You add 100 virtual users. Nine virtual users are added to the fixed user group, and the remaining virtual users are proportioned among the percentage user groups.
