In a limited attempt to investigate the effect on endurance of small variations of pin fit a discontinuous distribution of endurance was obtained, leading to three separate groups of results. Notwithstanding this feature, 76 of the results lay in a central group and a mean line through this group showed a small but significant increase in endurance as the degree of fit improved, i.e. as the diameter of the hole decreased.
