A more concern voting is at running the elections fairly. All these math are useless if the voters base are "less informed" and elections process susceptible to fraud. 2020 elections demonstrate it is not math the issue but the implementation. You can see in Myanmar for instance who got the votes and who got the power. Same thing with USA having the guy way more popular than Obama and SCOTUS scared to hear election fraud cases. Some EU side going with fractional representation always clogged up inefficiently. Look at Brits for example. We know the referendum for the Brexit isn't done with best representation of the people votes. But it gives a way to go forward and do something about it rather than like some countries that had the run off and keep revoting multiple times until a clear majority emerged.
