Deflect-O-Lator Rating Help

I went into the Deflect-O-Lator with my measurements and my inches on center is much larger than the drop-down menu allows. Here are my joist measurements: 5.5" tall; 3.5" wide; 7' long between supports and 48" on center in Douglas Fir. My subfloor information is: 1 1/2" thick T&G floor boards which are 5" wide. The subfloor runs perpendicular to the joists. Can you work this Deflect-O number out for me? If lower than L/720 what would I need to do to bring it up to L/720?
