I still did'n find a good answer. I'm sure that the calculated value is used by the ECU to manage the regeneration process, nut the measured value is stil mysterious for me: for example it can go down to negative values that are meaningless for me. Some users told me that in case of failure of some sensor, the measured value is the only one useful to understand the condition of the DPF system. In my experience I didn't tested that kind of situation, but trusting those users, I added the measured soot mass value to the app.
