If that is the program you are using then you can fly most duration
models in the 2-5% range provided the models are some what stiff. Very
floppy models like EZB tend to fly better with a range closer to 10%,
you can go less but the trim must be spot on or the site has to have
smooth air. Also for pennyplanes I use to go closer to 10% as well as
they were less troublesome with high torque launches. "Reg" is the name
of a friend of Bernie's (an aero engineer) who supplied him with the
formula for NP
