+| 8 |StressTester: method to set Qc2 running forever: the one algorithm repeats, e.g. continuous interpolation roots.   |OK, but not released |
+| 9 | SingleMinMaxAverage | **kvqc2_1.0.1** For a given paramid and corresponding Max paramid and Min paramid calculates a correction for an single missing value as average of max and min. If no max or min available or specified then reverts to simple linear. |
+| 10 | SingleLinear |**kvqc2_1.0.1** Replaces a single missing value with a linear interpolated value. If specified checks that the correction lies within the available max ... min range, if not sets to nearest of max or min. Run for any paramid and optional max, min specified in the configuration file. |
+| 11 |Null call ... does nothing.   |For testing only. |
