Interesting presentation, congratulations!

Just one question related to MCUs FMEDA and more precisely the PMHF total rate. I could not understand exactly which is its value. For instance on slide 34 there is the sum of SPF and RF resulting in 2,18 e-10, so way below the ASIL D threshlod and also fulfilling general commitment of MCUs within the total budget of PMHF rate (1%). But right below that there is another "total lamba ISO 26262" calculated which is three orders of magnitude bigger (10e-7 compared to 10e-10), furthermore on slides 17 and 18 there are some mentions about total MCU raw FIT rate (about 10e-6) and that they should relate somehow to ASIL B (actually the verbatim statement is : The objective is to make SW execution safe to achieve ASIL B) and then an arrow in the ASIL grading figure, pointing from MCU raw to ASIL B ..

What's the connection between all that? How much is at the end the total FIT rate for the entire MCU (PMHF metric)?
