I browsed through this, but it seems to me this text tries to solve 
two problems at once:

a- should VP scales be decimalised or rounded?
b- should the scales be linear or not?

It seems to me you don't need to do a lot of math to solve either 
question.

With regards to a-, you don't need examples to prove that sometimes, a 
higher number of IMPs will lead to a lower number of VP. That's just a 
consequence of rounding. If you want to do away with it, by all means 
do. I don't think the players object much to either.

With regards to b-, it is my opinion that if all teams play all 
boards, it should not be right for a good board to have a different 
influence when it is played in a match that is otherwise lost or in a 
match that is already blitzed.

My vote would be for straight IMPs, not even capped in matches. This 
is a serious tournament, right? So if you win by 25-0, you've earned 
that. In fact, I believe you've earned 30!
