Documentation
Definition
The variance field specifies whether or not the various processing blocks in a program are currently called (that is, called in the current program form) with similar frequency.
A best possible distribution will return variance values of 62.5 to 83.3.
Values of 1 to 5 indicate a strongly asymetric call frequency.
A value of 0 means only one processing block, or none at all, is called.
To calculate the variance, the processing blocks are sorted by their call frequency and the results are converted to a probability distribution with the interval [0,1]. The resulting variance for this distribution is then multiplied by 1000 so that an easily legible number range exists.
