Can someone answer this:

What would my .32 size come out to be? The charts I found state the following:

Alternate Propellers Starting Prop Engine Size
9x7,9.5x6,10x5 9x6 .20 - .30
9x7,10x5,11x4 10x6 .35 - .36

With the .32 being in the dead-center of these sizes which should I choose? 9x6 OR 10x6. Is this the case where the higher size prevails the same way shoe and clothes sizes are determined?
