    Reduction because of what? Reduction from what to  what? 
 
    What actual mechanical improvement does the  additional mid-bearing make? 
More torque reduction? No. More vertical weight  reduction? No, the weight's 
already on the top bearing. A psychological  improvement? Probably. More ham 
radio old wive's tales? Probably.
