I am not sure you correctly understand the meaning of the numbers, but you 
are right, it produces wrong answers.

We will need 4 stats:
1. The number of available passengers at any given moment.
2. The number of available boats at any given moment.
3. The number of passengers who were looking for baots (successful or 
not) this turn.
4. The number of boats who were looking for passangers this turn.

The use of the first 2 numbers is clear --- so we don't do expensive PFing 
when there are no p/b to be found.

The use of the last two for build planning, and should be somehow 
averaged.

I think these stats should be kept in AI data.
