I wrote a test script for the estimation routine.

It divides the whole table extent into query cells
and queries the db. This is done with boxesPerSide
going from 1 to 40.

So the first level will make a single query,
the second level will make 4 queries, then 16 ... up to 40*40.

I send it as an attachment here, so I hope we can have a better
look at what it's going on.
