> If, at any time in counting process, an individual could successfully insert a single valid but fabricated ballot into the process

This varies by jurisdiction obviously, but where I'm from the procedure for counting must be done in an area which the public can access and it begins with a single person taking ballots out of the box one by one and giving it to a chain of 2-3 other people.

This way you can count how many ballots were taken out of the box and check with the totals at the end

And obviously the box is always in the presence of observers from various stakeholders

> less than 43,000 votes

Unless you can predict where these tiny margins will manifest with perfect accuracy you'd need to add a lot more fake votes, or at least have thousands of conspirators ready to add them at a moment's notice, that's ridiculously hard to organize discreetly
