Figure 23 illustrates the relationship between
vmax/vmin and the design factor, the plotted boundary
curves being valid for an equal degree in k. Their
shape manifests the amount of necessary reduction in de-
sign factor to assure a higher vmax/vmin ratio for
k,3 = constant.

As a result of the sweeping application of the latest
auxiliary means, high-speed ratios of 4.0 and more have
been obtained and this applies to all entries with few ex-
ceptions. The best figures here were those of the already
