a quick formula to go by: 2-3 fps for every pound short of 70 and 10fps for every inch short of 30'' ...so shooting 53 pounds your losing between 34 to 51 fps off ibo speed, and add another 20 fps for the 28'' draw...

so somewhere between 54 and 71 fps off ibo rating of a new bow is the speed you would be looking at...hope this helps
