But in certain circumstances, such as those in Makman's video, you may need to change course in order to obtain a non parallel bearing and increase accuracy of the solution.

Kuikueg , check your pm
i insist that if you DON'T CHANGE COURSE AND SPEED the fourth bearing will be ALWAYS the red line !
all these only at the situation that you haven't change COURSE AND SPEED
you say: ''

this point is not correct,imo, Kuikueg. if you draw a straight line for your course then the spaces between the time intervals will not be equal (which can be 'translated' as a 'speed' change)
