- *
- * The advantage of this approach is that we only need 1 variable

- * the average will not decrease fast enough to compensate.
- * The walking average compensates this and will move towards
- * the new values correctly allowing a effective link tuning,
- * the speed of the average moving towards other values depends
- * on the value for the number of samples. The higher the number
- * of samples, the slower the average will move.
