Hallo,

Example 4:

   10 ABCD
   15 BACD
   20 CABD
    3 ABCD

   Suppose Craig Carey's IFPP method is being used.

   In the first round, the quota is 12. D is eliminated in the
   first round. In the second round, the quota is 16 so that A
   and B are eliminated and C wins.

   When 7 C voters are added, then this situation looks as
   follows:

   10 ABCD
   15 BACD
   20 CABD
    3 ABCD
    7 C

   Now in the first round, the quota is 13.75. A and D are
   eliminated in the first round. In the second round, B
   beats C.

   This example demonstrates that IFPP violates mono-add-top
   and mono-add-plump.
