Below are the results from my tests a year ago on my newer-model E39.

Note that the forward biased readings are different from the reverse-biased readings, which, if someone is having problems, should be looked for to see if they're using the correct technique (most of them aren't).

So, to stave off confusing for the people who use the diagram we created today, I just now added (in red) a note about the biasing directions.
