Calculation is correct now. It turned out to be really, really complicated. One the one hand the community protection levels per round change as a result of NewsEffects, while on the other hand the discount of houses is introduced in a round. When either of these methods are introduced, floods might already have occurred, and could even have been superseded by new floods (that would not have been a flood before the NewsEffects changes). The first discount takes effect the round after the flooding happened.

The results look, e.g. as follows table has also been made more clear):

In the above example, only Natucity had a discount rule from round 2 onward (and the protection weakened from round 3 onward). As expected, discounting takes place in round 3 with the first 10 k.

When we change the river flood level to 10, no discount is applied:

When we change the flooding to happen in round 1, correct discounting is applied:

And when the flooding takes place in both round 1 and round 2:

Calculations look correct.
