And of course, the electrons escape out of the bottom legs of the 'm' much faster, whereas they're trapped in the 'w's until enough of them amass and they can climb out.
You don't need to switch to 'm' to fix this; quantum annealing will do the trick. Just turn up the color temperature on your monitor and the electrons will tunnel through the sides of the 'w's. That's how the DWave machine works.
The rest of your comment is spot-on, though.
