I don't think so, In your example A has less than 50% of the votes so the country with least votes (C) is now eliminated and the second choice of each of those votes is distributed. If 15 or more went to B then B would be the preferred choice of over 50% of those voting (rather than A) and would win. If some of the votes for C have no second choice then these votes are just discarded (the voters are indifferent as to whether A or B wins) and the number of votes needed by either A or B to win becomes 50% of the new total votes cast
It is similar BUT transparent (everyone can see and understand how it works) rather than the rather opaque system where you 'put it into the computer' to see who has won - which looks very difficult to understand for those not so mathematical y inclined. Especially as you can apparently get 'tied' results' !
There are some other, slightly more complex reasons why STF is preferable - basically it encourages you to express your second choice (and third if there are 4 candidates etc) in all circumstances, which is not true of the present method.
Actually that's not quite true.
32 votes A>C>B
26 votes B>C>A
22 votes C>B>A
As you can see, STV would give B as winner.
However Condorcet realices that 48 voters prefer C to A and 54 voters prefer C to B. Therefore >50% prefer C to A and >50% prefer C to B. Thus C is the Condorcet winner, whereas it would have been eliminated earlier during STV.
Condorcet favours compromise options (everyone is a bit happy), whereas STV favours extremes (some are very happy, some are very unhappy). This is extremely important when deciding our next ETC destination IMHO.
Condorcet is somewhat more protected against tactical voting than STV (Which has been a huge issue in the past), and in Condorcet it is more important to state all your 2nd, 3rd choice than in STV, because the 2nd, 3rd.. choices are used always in Condorcet whereas only sometimes in STV.
Condorcet can be mathematically calculated, although it is indeed a bit tougher than STV.
Condorcet, just like STV, is subject to ties, and there are several methos for solving those. Both of those system's tie-breaking methods are also mathematically tough (at least if you want a decently fair tie-break)
Really, trasparency is all about stating all the voting rules prior to the vote, blinding vote submission (To minimze tactical voting) and public posting of the ballots and results afterwards. Being mathematically challenging is not being opaque. Anyone with the knowledge or an appropriate app can recalc and double-check the results. If you want more in-depth info regarding voting systems, perks and flaws, and how to work each of them out, there is ample info on the net, but I can also guide you if you so prefer.
That said, if the voting system is to be changed, simply call for a CCC vote (remember to include tie-breaking system in your proposal).
