   The MEAN, most PROBABLE result of the measurement result being +1 or -1   
   conforms to the sign of the dot product, but only the probability.  For   
   example, if the vector 'a' differs from the previously selected spin   
   vector 'e' by an angle of 85 degrees, the dot product will have positive   
   sign, but the result of the measurement of many electrons will be nearly   
   54:46 for +1:-1 results, not all +1.  The probability ratios will go as   
   (1+cos(theta))/2:(1-cos(theta))/2 for +1:-1 probabilities.
