Okay, here is the latest from LimeWire development versions: The number of results when GUESSing has been set to 250 actually not 200 as I said before. However GUESS is complete yet and it might be changed.

The number of results next-gen ultrapeers return when being queried has been set to 150 at the moment. The number of ultrapeer connections for leafs will be set to 2 by default.

The number of leafs for ultrapeers has been reduced to 40, the number of ultrapeer connections for ultrapeers have been increased to 47.
