By the edge of the strip, I mean the edge TOWARD the center of the board. The edge immediatlely in front of the gold pad, which the carbon is sprayed onto. We want the area right at the seam of the edge of the gold pad.
You want the brush to be right at the green line for minimum dead space.

The brush marks are very slightly back behind the line. That very slight difference on the circuit board, equates to a huge movement of the gas pedal. It's all about leverage, think about it. The slight bending of the brushes gets rid of that space between the green line and the former brush marks.

This is all making sense to me up to the point of WOT. Since this is a mechanical issue, the brushes are designed to start at one point and end at another. By bending the brushes, the contact is made sooner giving a better pedal response, but it will also stop the brushes earlier at the other end due to the new angle. Would the ECA compensate for this or are we robbing fuel at WOT by not allowing the brushes to continue to the originally designed spot at the end of the strip?

Nothing is different at WOT, in fact, theoretically it would be a more consistant full throttle after the brushes were bent. You see, once the brushes get to the end of the carbon strip, they run into those gold pads, and once the brush is over the top of the gold pads on the other side, the ECU will always send the WOT signal to the throttle body.

Exactly. Thats why the travel stop works much better than the bending method.

I have a question.
By changing the angle of the brushes, we are changing the area where the brushes contact the track. My question is what happens if we adjust these brushes too far and they contact the Plates on the other side of the track. this would happen under a WOT scenario. I have modded your pic to clarify my question.
