+=+ Your problem here Konrad has to do with the VP scale.
If it leaves a gap between 65 imps and 66 imps without
saying how to deal with any score that falls between the two,
it is flawed. That applies however an imp result is obtained
that is a fraction of an imp above 65 imps.

Good. So if I am about to award average plus to a contestant
whose final score for the 20-deal session is
62 IMPs then he will get...?

For the rest of the 19 deals he averaged
3.2631578947368421052631578947368 IMPs per deal.
If you think that giving him
3.2631578947368421052631578947368 IMPs for the 20th deal
as average plus which will make the contestant's final
score for the sesson
65.263157894736842105263157894737 IMPs
is the right answer then please tell me what happens if
the final score is supposed to be converted to VPs.
Say it is a team match.

According to the official IMP-VP scale for 20-deal matches
a difference of 60-65 IMPs is a 25 : 3 VP win
while the difference of 66-67 IMPs is a 25:2 VP win.

What do you do if a team won a match by
65.263157894736842105263157894737 IMPs?

All this really hasn't been given a thought by the
lawmakers.

I'd really like to see it explained more clearly.
