MercedesShop? There was a HUGE thread on that over there... At the end of the day, I don't think it's useful for setting the timing. It basically boiled down to "is the highest combustion temperature really what you want for ideal timing?" "Possibly" is the best I can answer that with. Also, as I'm sure you're aware, measuring less than 20mV with a standard DMM is pretty silly. If you had something to measure thermocouples you could be alright though (thats what the glowplug is acting as).
