I'm going to focus only on your claim that this page shows an example
of the violation of monotonicity by Manoj's proposal.

Monotonicity (http://electionmethods.org/evaluation.html#MC) requires
"With the relative order or rating of the other candidates unchanged,
voting a candidate higher should never cause the candidate to lose,
nor should voting a candidate lower ever cause the candidate to win."

But, on your page, I don't see any examples of "voting a candidate higher
with the relative order or rating of other candidates unchanged".

Instead, I see one example of an introduced vote where B, C and A
are all changed with respect to the default option.
