A few things... One to see if how traffic is flowing... sure you can 
look a the numbers go
up but to be able to start from zero gives you a better idea on how well 
things are flowing.
I also use it for testing patchs that deal with caching or  RPC changes 
to see what impact
they have on OTW traffic...  Another use it to see what opts are really 
being tested... Starting
up a test run, zeroing out the stats give you a very clear picture of 
what exactly is going on...
There probably a few more uses that are just not coming to me right 
now... Its one of those
tools that I keep finding ways to use... :)
