20x20x20x20x20=3,200,000 with very little end user and traffic.
As contrast, 160 000 x 3 = 480,000 for all com/net/org with end users and traffic.
So you need to narrow the field even further beyond the CP concept. Hence the patterns and their depletion within LLLLL CPs. Someone comes with new pattern, it is bought out then they move to next one. I am just going to be an observer in this game )
