Special categories in the Giro d'Italia

In the first Giros, there were special categories of riders. In 1950, there was an overview of winners of special categories published in a newspaper (source), but it did not say which category they won. Below an attempt to see if this overview was a bit correct.

The general conclusion is that the list shows the isolati from 1909 to 1936, the best free rider (isolati or grouped) in 1937, the best grouped rider from 1938 to 1940, and the best cadet/independent rider from 1949 to 1950. A few differences that are not really a problem:
