Bill,
I would agree with everything Mitch said, but especially with the usefulness of the '-1' option. This is a feature I did not know about until I came to CDM.
The output of EPA SWMM and XP-SWMM are about the same using STATS. The STATS output is essentially Don Pollman's and Wayne Huber's creation in the middle 1980's and it has not changed much since then except for a few bug corrections.
I would however suggest that a better C1 line for STATS is the following:
* Request for total flow average flow peak flow event duration
interevent duration
C1 1000 1000 1000 1000
1000
Best Regards,
