Honestly sounds on the low end...but I've known of chronographs hurting a lot of people's feelings. They think they are approaching 200 fps, when the chrony says a whole lot less.
If you haven't done them already, there are lots of ways to improve performance. A big one that Rod Jenkins mentions on his site (
www.safarituff.com) is work on your release. A good release can make a big difference in speed, noise, and accuracy. Get a well made string. A good string served to fit your nocks can make a good bit of difference. Tuning is a biggie also.
To get an idea of what your bow is capable of, you need to find someone with a Hooter Shooter. It won't short draw, make a bad release, vary, etc. Anything else is an (educated?) guess. Also, be sure your chronograph is properly calibrated and the light conditions and shooting distance is correct.
