The impact of market change element shows the effect of the change of the total "market" (total dataset sum) size. This will be zero if there was no change in the total market size between year zero and year one. In the case above, the share would have grown by about 33/34 points if the total market of year zero and of year one had stayed the same. Since the market grew in size, the share actually shrunk by six points, the difference between -40 and 34.
