I'm probably missing something simple, but I can't get the numbers to add up.
44% of 531M shares is ~234M Votes
50% of 301M shares is ~152M Votes
These two numbers should equal one another, if I understand your explanation correctly, and they are roughly 100M apart.
The table represents the voting power of the individuals named. All 7 total up to roughly 46%. This seems like very straight forward addition of the values given. The category is even called % of voting capital.
In the 14c they state that the vote carried with the 7 individuals and 50.42% With the numbers given, I don't see how that is possible. Either there is another voter that has been omitted or the numbers were reported incorrectly. With such an exact number, I don't think this was malicious, but something has been left out or I'm way off.
