That's quite the odd result. I've had overshoot, but never 340 degrees. Largest overshoot tends to happen on smaller pans. Most of my regular pans might have 5-10 degree overshoot that stabilize once the pan comes down to temperature (it seems like the CF software is "smart" and adapts once it learns how the pan heats up and responds to changes in power).
Also the pattern is odd as it over heated on the edges.... I'm wondering if the center of the pan did not make proper contact with the through-the-glass temperature sensor (like it was warped?)... so the machine kept heating up and up and overheat the sides that were making good contact with the glass and hence affected by the induction element? Just guessing...
