How To Figure CFM from Sensible Heat Loss/Sensible Heat Gain

I am performing a Manual J Residential Room By Room Calculation Load By Hand.

Dinning Room

Sensible Cooling Load: 8,418 B.T.U.H

Sensible Heating Load: 11,453 B.T.U.H.

I don't exactly understand how to do this?

400 CFM Per Ton (12,000 B.T.U.H.)
Whole House Load is 3 Tons (1200 B.T.U.H.)

Should the CFM be figured to match the sensible cooling load or the sensible heating load (which is 3,035 B.T.U.H. more)?
