To sort out the controversy of the 1938 point scores, it might be easier to understand if we look at one race at a time and sort out the problems at this one event until agreement is reached - if at all possible. Only thereafter discuss the following event.
Below are the tables of the four races. A.-R. = AUTOMOBIL-REVUE; Snellman = Golden Era. There was no points contradiction at the first race.
Please support your arguments with sources. Conjecture will be a dubious way to reach a valid conclusion.
