I can see nothing that could be excluded.

It's unnecessary to do the math because A, B and C reach the quota. You can
declare the result and have a coffee or whatever.

What do you propose to do if you use the Hare quota and there are four
rather equal candidates vying for three seats: 25.1% A,   25.1% B,   25.1%
C ,   24.7% D?
