The general averages for the two squads are plotted in figure 104. The main interruption in the improvement shown by Squad A was on January 12, as previously mentioned. Considering the points from which the two squads start, each improved approximately the same amount. The curves are regular and of the usual practice form. It will be noted that Squad A, on their one normal date, were at a higher level than Squad B, the difference being 10 points in favor of Squad A.

In the two succeeding experiments, however, which were during reduced diet, Squad A failed to maintain this advantage and improved relatively slower than Squad B. During the low-diet period, Squad B also made but a minor improvement, almost all of which was on the last date. It appears, therefore, from the data at hand, that improvement in efficiency for quickly and accurately locating and cancelling desired number combinations in heterogeneous material is not favored by the condition of reduced diet.
