Eliot, it is not really a trick question. It is an illustration of what is the best mode of learning. Learning to dovetail is not mathematical, and it is not practice (I never practice or warm up). It is visual spatial.

For someone to retain information, it needs to be understood. The Big Picture, so to speak. This allows one to make decisions, such as how to strategise. Starting at the corners is just a strategy. Looking at the big picture first is where we start.

You need to understand why you do what you do, otherwise you be starting afresh each time, and this attacks confidence.

Dovetailing is a collection of parts making a whole. It is helpful to understand how they come together and integrate. One needs to break the sequence down, recognise the parts one must focus on, but always with the understanding how they come together.

For example, the baseline is scored and must not change when chiselling the waste. I create a chisel wall before fretsawing the waste out, as it is easier at this stage to do so (than when there is a stub of waste).

Understanding the relationship of the pin to tail, makes the importance of the square cuts at the edge of the board stand out. So score these deeply, and use the saw cuts to guide the blade.

Accuracy of sawing is assured when you follow two lines together (top of board and the diagonal). Sawing a single line will get you into trouble. No amount of sawing practice will prevent inaccurate sawing if you do not recognise what lines are important.

A knife line is less than 0.1mm wide. I saw to the line. I understand the consequence of sawing over- or short of it. The two-line focus helps the saw track accurately. 99% of my dovetails fit without adjustment.
