All in all, I think the sensors are a good way to know when to replace brakepads.
But you have 8 brake pads, and only two sensors. If a caliper gets slightly stuck, a pad could be down to the metal before the one with the sensor is triggered. I also noticed that a half worn pad will fade faster than a new one. I think the heat capacity is simply too low due to reduced mass and thickness. That is why I don't like to wear the pads 100 percent down.

I don't know yet for the F20, but on earlier cars I have had 2-3 sets of pads per disc.
