Nelson and Jellicoe adapting to circumstances

Is there a useful comparison between Nelson accepting revised signal wording and Jellicoe changing direction?

Yes. Both accepted necessary changes and dealt with the circumstances they faced.

Both commanders are credited with accepting changes when circumstances required them. The comparison links Nelson's acceptance of revised signal wording with Jellicoe's change of direction. Effective command requires responding to what is possible, rather than insisting that events follow the original plan.
