Pairs, XIMPs and Weighted Scores

Can somebody please check that the following calculation of a Weighted Score in a Pairs competition that is scored using the XIMP method?

With 4 'normal' scores of:-
+1430
+680
+650
-100

and 1 'Weighted Score' of 50% of +1430 and 50% of +680,

I make the XIMPed scores for the normal results as follows:-
+1430 +13.00
+680 -2.00
+650 -2.50
-100 -14.50

and the Weighted Score with a nominal value of +1055 (50% of 1430 and 50% of 680) I calculate to have an XIMP Score of +6.00

Is this correct, if not what is the correct score?

    No, you don't weight the raw scores, you weight the IMPs. The correct score is 5.5.

    You score each result against each other result, remembering that the two largest scores have frequencies of 1.5 each, then divide the totals by the number of comparisons (4).

    It gives you scores of

        1430  :  12.375
         680  :  -1.375
         650  :  -2
        -100  : -14.5
        W/S   :   5.5
