I wouldn't like to refer to it as a weighted vote, although mathematically you could consider it as such. As I've tried to explain, the rationale for it is that you are not voting your own single vote. You're voting all of the votes that have been entrusted to you, and that is true for all of the members, and everyone's vote is entrusted to somebody.
So, yes, you could say that's a weighted vote, and indeed, there's even a stronger reason for thinking that it might be considered in that way, because one of the issues with respect to the matter is that it could be that there are constitutional issues where some provinces may be guaranteed a certain number of seats. My solution to that one is to derive the equivalent seat total that each member would hold in trust by using the total vote and doing a simple calculation, to say so many votes is equal to so many seats. We're talking, of course, about fractional seats. And so, within Parliament itself, you would need computers to keep score of either the citizens' votes or the equivalent seat total votes instead.
