Trapezium instead of the Circle of Work

As learner bell ringers progress from rope handling to call changes, then plain hunting, they will eventually arrive at the task of learning Plain Bob.

The big new challenge in ringing Plain Bob is the quick change from holding up and cutting in, known in the lexicon of bell ringing as "dodging", while hunting up AND hunting down! While coping with this tricky handling technique, the learner also needs to know when to switch to the other "works", namely "making seconds" (following the treble twice in a row) and "long fifths" (normal ringing for four blows), and in the correct order!

The bell ringing literature is full of references to "Circle of Work", best described graphically as

Even with this logical visual presentation, I had a lot of difficulty to very quickly determine while ringing what the next piece of work should be. It may take just a second, but in bell ringing that can be an eternity as one also has to manage the rope at the same time. Very often I ended up a bit slow or being totally confused as I lot count of my position.

After some thoughts I realised the "Circle" is not descriptive enough to help one's memory because all the four pieces of "work" look so similar in it.  Instead, I devised the "Trapezium of Work" as follows:

By showing the same objects as a trapezium rather than in a circle it makes it so much more intuitive. The slopes help the learner to remember whether it is to hunt up or hunt down, and the longer base line obviously denotes the long fifths. It is certainly quicker to recall while busy pulling ropes at the same time!
