I wish it did measure something so the prediction of changes is more accurate.

My experience with VW TDI fuel filters has been just the opposite. You could actually see the dirt in the element and a substantial area still clean inside the filter when it came time to change. Dunno about the BMW filter, since I rarely found water also. I would just follow the manufacturer's guidelines unless I knew a good reason that the fuel was bad.

When I drove from LA to Chicago some of the "diesel" was weird looking (topped off). I was in my old TDI and brought a supply of additive as placebo.

Pierre has an active imagination with apparently, a lack of any practical knowledge or experience to back up his comments:

Au contraire Pierre, your imagination regarding diesel soot and certain regeneration events with what's happening upstream of the DPF is clearly misinformed by an active imagination. |

But certainly the presentation had no data and what he said about EGR (and soot contamination) causing a "25-30% decrease in fuel efficiency" in diesels is a wild exaggeration. The usual quoted decrease is about 3%: see this reference: Quote:
