Steadily increase strongholds size with team size

`groupedDistance` is the "distance between neighboring players" but it
was used as the radius.
Then there was a special case when the team size is big and the
`groupedDistance` was to small.

With this commit the `groupedDistance` is actually used as
"distance between neighboring players" and removes the special casing.
