Hi, Awesome ;) JMeter is already my fav stress testing tool, and it keeps getting better all the time. I wish I had more spare time to help with its development ;) Kudos and thanks to Senor Lin and the other JMeter contributors.
As for the load factor: pretty much anything is better than nothing. Please retain the description of this factor somewhere in the UI so users can know what it means (doesn't all have to be on the main page: can be a link, a mouse-over text, etc.).
