straight line for the whole move IIRC. So from the point where the furthest moving corner starts to where it ends

I think this was discussed in another thread at some point and noted that this has a problem where wheels over 180 start to cost less movement again. I think some resolution was suggested to avoid this.

"For ease of measuring, the distance moved during the wheel is taken as the straight line from the starting position to the ending position of the moving front corner. "

NOT

"For ease of measuring, the distance moved during the whole moveis taken as the straight line from the starting position to the ending position of the moving front corner. "

Besides, "the moving front corner" would give you two possible move distances if you combine the wheel with some forward movement as both corners move (it does not say furthest moving corner ). During the wheel, one corner is stationary so there is only one moving front corner. Hence "the moving corner" makes unambiguous sense.

No wonder Dave's LH seem to move like greased lightning.

Which refinement of my understanding has now made wheels much harder to measure.

In my defence, which I am doing a lot of lately, I had not played FoG until I got to Manchester, where they had been playing at least a year. Obviously had I stayed at Reigate I would not be foolish enough to admit to such shenanigans.

Do you mean that this is legal:

(dashed unit is ending position)
A wheel over 270 degrees becomes a wheel back.

Technically this is legal. It is recognised that it should not be legal and was the subject of another thread some time ago IIRC. This is not affected by the difference of interpretation we are discussing in this thread. It only works if there are no obstructions in the swept-out area.
