So from what I understand, Apache status will display more than minimum server limit but will add more once spare threads is hitting the threshold. I currently have 18 childs with 64 threads per child but I should expect to see more child processes spawned if there are less than 800 idle workers. Idle workers are spare threads identified as "_" Waiting for Connection.
Does this sound right?

The numbers might not be perfectly round because the server is not frozen while mod_status iterates over everything. Apache will spin up a 17th process when there are less than 800 idle threads.
