The Use of Activity Records as Data for Eliminating Fatigue.
The fact that activity records are made of extremely small elements moving through a short path in a small amount of time means that the fatigue records cover the same short periods. This is a great help in making fatigue study. A new combination of elements of activity will also mean a combination of concurrent, or included, elements of fatigue. The combination may have some effect on the activity. If so, it will also affect the fatigue, but at the present state of the art the most accurate and satisfying work can be done by making use of activity records to eliminate unnecessary fatigue, without waiting for some hypothetical, direct records of fatigue, that may be worked out in the future. In other words, if you have accurate records of fatigue included in your activity records, use these immediately, without attempting to make separate records of the fatigue, that, while valuable, will mean delaying fatigue elimination, perhaps indefinitely.
